Product details
Overview
SN75116NS from Texas Instruments is a dual-function differential line transceiver integrating a 3-state differential driver and a differential-input receiver in one IC, operating from a single 5-V supply. It features ±15-V common-mode receiver input range, TTL-compatible I/O, dual data inputs (AND/NAND), optional internal 130-Ω line-termination resistor, and receiver frequency-response control (RTC) pin - enabling robust party-line bus communication in industrial backplanes and legacy data buses.
For engineers reviewing the SN75116NS datasheet, SN75116NS pinout, SN75116NS application, or SN75116NS equivalent, key selection considerations include its open-collector/totem-pole output configurability, independent driver/receiver sections, strobe-controlled receiver output, and compatibility with RS-422-style differential signaling over noisy long traces.
Technical Context
The SN75116NS implements a fully independent driver and receiver architecture: the driver accepts dual TTL-compatible inputs (DA/DB) and provides selectable totem-pole or open-collector outputs via separated DZP/DZS and DYP/DYS terminals; the receiver features differential inputs (RA/RB), ±15-V common-mode tolerance, internal 130-Ω termination option (RT pin), and frequency-response control (RTC) for noise immunity tuning.
Its receiver output is strobed (RS pin), not 3-state enabled - distinguishing it from SN75118/SN75119 - and delivers TTL-compatible logic levels at up to 15 mA sink current. The device supports party-line bus topologies by allowing multiple transceivers to share a single differential pair, with driver disable (DE) and receiver strobe (RS) providing precise timing control for collision-free half-duplex operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation across standard TTL power rails with ±10% tolerance. |
| Receiver Common-Mode Range | ±15 V - enables reliable reception in electrically noisy environments with ground potential differences up to 30 V between nodes. |
| Driver Output Current | ±40 mA - supports direct drive of unterminated 100-Ω differential lines or termination networks without external buffers. |
| Receiver Propagation Delay | 20–75 ns - guarantees deterministic timing for synchronous bus protocols operating up to ~10 Mbps on short-to-medium traces. |
| Internal Termination Resistor | 130 Ω (typical) - reduces external component count and improves signal integrity when used as end-of-line termination. |
| Frequency-Response Control | RTC pin adjusts bandwidth - allows trade-off between speed (fast edge) and noise rejection (slower edge) via external RC network. |
| Operating Temperature | 0°C to 70°C - qualified for commercial and industrial ambient environments, excluding extended military ranges. |
Pinout & Package
SN75116NS is supplied in a 16-pin plastic DIP (N) package per JEDEC MS-001. Pin functions are validated per TI SLLS073D datasheet Figure 1 (top view).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DZP / DZS | Driver output pull-up / sink | Separated totem-pole terminals - enable open-collector mode (DZS only) or full totem-pole (DZP+DZS tied). |
| DYP / DYS | Driver output pull-up / sink | Second driver output pair - supports dual AND/NAND logic functions with DA/DB inputs. |
| RA / RB | Receiver differential inputs | Accept balanced signals; tolerate ±15 V common-mode voltage relative to GND. |
| RT | Termination resistor control | Connects internal 130-Ω resistor between RA and RB when grounded - eliminates need for external termination. |
| RTC | Response-time control | Adjusts receiver bandwidth via external capacitor - reduces sensitivity to high-frequency noise or overshoot. |
| RS | Receiver output strobe | Active-low enable - gates RY output; used for synchronized sampling in multi-drop bus systems. |
| DE | Driver output enable | Active-high - places driver outputs in high-impedance state to prevent bus contention. |
| VCC / GND | Power supply | Single 5-V rail powers both driver and receiver sections - simplifies PCB power design. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-driver logic configuration | DA/DB inputs support AND/NAND functionality - enables encoded bus arbitration or status multiplexing without external gates. |
| Configurable driver outputs | Separate DZP/DZS and DYP/DYS pins allow user-selectable open-collector or totem-pole operation - adapts to legacy bus standards requiring wired-OR or push-pull drive. |
| Integrated line termination | 130-Ω internal resistor (enabled via RT pin) matches typical twisted-pair characteristic impedance - minimizes reflections on point-to-point or daisy-chained buses. |
| Strobed receiver output | RS-controlled RY output enables synchronous sampling - critical for deterministic timing in time-triggered or polling-based bus protocols. |
| Receiver frequency-response tuning | RTC pin accepts external capacitor to adjust slew rate - balances signal integrity against EMI susceptibility in mixed-signal enclosures. |
Applications
| Industrial Backplane Bus | Legacy Data Acquisition System |
|---|---|
Use Scenario: Multiple sensor nodes communicate over a shared differential bus in a factory automation rack, where ground offsets exceed 5 V between slots. IC Role / Device Role / Timing Role: SN75116NS acts as bus interface transceiver - driver transmits local node data; receiver captures upstream commands with ±15-V common-mode rejection. Use Value: Eliminates need for isolated power or level-shifters; internal termination and strobe synchronization reduce jitter and improve sampling accuracy across 16-slot chassis. | Use Scenario: Retrofitting an aging SCADA system using RS-422-like signaling, where new nodes must interoperate with original master controller hardware. IC Role / Device Role / Timing Role: SN75116NS serves as drop-in physical layer translator - converts TTL logic to differential pairs and vice versa while preserving timing relationships. Use Value: Dual DA/DB inputs replicate original gate logic; RTC pin compensates for cable-induced ringing on 100-m runs without redesigning firmware timing windows. |
| Military Ground Vehicle Data Link | Test Equipment Subsystem Interface |
Use Scenario: Communication between avionics modules in a tracked vehicle, subject to engine EMI and vibration-induced ground bounce. IC Role / Device Role / Timing Role: SN75116NS provides hardened differential I/O - driver drives shielded twisted pair; receiver decodes commands with strobe-gated sampling to reject burst noise. Use Value: ±15-V common-mode range handles chassis ground shifts during ignition; internal termination maintains signal fidelity despite connector wear over 10,000 mating cycles. | Use Scenario: Interfacing digital pattern generator outputs to a DUT requiring differential stimulus with precise edge control. IC Role / Device Role / Timing Role: SN75116NS conditions and transmits test vectors - driver configured as totem-pole for fast edges; receiver strobe synchronizes capture to system clock. Use Value: Configurable output type and RTC tuning allow optimization for either speed-critical setup/hold or noise-immune validation phases within same hardware. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar differential line transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN75118N | 3-state receiver output (RE pin) instead of strobe (RS); identical driver section and pinout. | Suitable for systems requiring receiver output tri-state control (e.g., bidirectional shared bus), not strobed sampling. | Select SN75118N if receiver output must be disabled independently of driver - e.g., in full-duplex repeater nodes. |
| SN65176BN | RS-485 compliant; integrated failsafe bias; no internal termination or RTC; 3.3-V/5-V tolerant I/O. | Designed for modern multidrop networks with automatic direction control; lacks dual-input logic or strobe timing. | Choose SN65176BN for new designs targeting RS-485 standards and lower power - but requires external termination and offers no logic-level encoding. |
Compared with SN75118N and SN65176BN, the SN75116NS uniquely combines dual-input driver logic, strobe-synchronized receiver output, and field-tunable frequency response - making it irreplaceable in legacy party-line bus architectures requiring deterministic sampling and hardware-level arbitration.

FAQ
What is the function of the RTC pin on the SN75116NS?
The RTC (Response-Time Control) pin on the SN75116NS adjusts the receiver's bandwidth by connecting an external capacitor. Increasing capacitance slows the receiver's edge rate, improving noise immunity on electrically noisy lines - a critical feature for stable operation in industrial motor-control cabinets or vehicle chassis where EMI is severe. This behavior is documented in TI SLLS073D Section 7 and Figure 7.
Does the SN75116NS support true RS-422 operation?
Yes, the SN75116NS supports RS-422 physical layer requirements: differential driver output with ±40 mA drive capability, ±15 V common-mode input range on the receiver, and TTL-compatible logic thresholds. While not formally certified to RS-422, its electrical characteristics (VOH/VOL, tPLH/tPHL, and noise margin) meet or exceed RS-422 specifications for point-to-point and multi-drop configurations up to 10 Mbps on properly terminated lines.
Can the SN75116NS driver outputs be used in open-collector mode?
Yes - the SN75116NS driver provides physically separated pull-up (DZP, DYP) and sink (DZS, DYS) terminals. To configure as open-collector, connect only the sink pins (DZS/DYS) to the load and leave DZP/DYP unconnected or tied to VCC through a pull-up resistor. This configuration enables wired-OR bus arbitration, as confirmed in the "additional features" section of TI SLLS073D and Function Table on page 3.
What is the purpose of the RT pin on the SN75116NS?
The RT (Resistor Termination) pin on the SN75116NS enables or disables an internal 130-Ω termination resistor between receiver inputs RA and RB. When RT is grounded, the resistor connects - matching typical twisted-pair characteristic impedance and eliminating reflections on end-of-line receivers. Leaving RT open disables termination, allowing use as a mid-bus node. This is specified in the Absolute Maximum Ratings and Electrical Characteristics tables of TI SLLS073D.
How does the SN75116NS differ from the SN75118N in receiver control?
The SN75116NS uses an active-low strobe (RS) to gate the receiver output RY, whereas the SN75118N uses an active-high enable (RE) to place RY in 3-state. This means SN75116NS asserts valid logic only during the strobe window - ideal for synchronized sampling - while SN751118N allows continuous output with tri-state control for bus sharing. Both share identical driver functionality and pinout, per TI SLLS073D revision history and functional diagrams.
