Product details
Overview
SN55113J from Texas Instruments is a military-grade dual differential line driver IC with 3-state outputs, designed for party-line bus applications requiring high-impedance isolation, TTL compatibility, and operation across −55°C to 125°C. It delivers ±40 mA output drive, supports single 5-V supply, and features individual and common output controls for precise bus arbitration.
For engineers reviewing the SN55113J datasheet, SN55113J pinout, SN55113J application, or SN55113J equivalent, this page provides verified technical context, military-temperature-rated specifications, dual-channel differential driver functionality, open-collector/open-emitter flexibility, and direct substitution guidance for legacy bus interface designs.
Technical Context
The SN55113J implements two independent differential driver channels, each with AND/NAND logic outputs and separate sink (YS/ZS) and active pullup (YP/ZP) terminals on adjacent pins-enabling true differential signaling without external components. Its output stage mirrors TTL totem-pole architecture but exposes internal nodes for flexible termination and biasing.
It integrates clamp diodes at all inputs and outputs, short-circuit protection, and dual-level output control (per-channel C and global CC), allowing dynamic bus release in multi-drop configurations. The device is fully characterized for military temperature range and requires no external pullups when used with SN55115 receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - Ensures stable operation with standard 5-V TTL rails and tolerates ±10% regulation drift. |
| Output Current (IOL/IOH) | ±40 mA - Supports direct drive of 50 Ω transmission lines or multiple TTL loads without external buffers. |
| Propagation Delay | 12–20 ns - Enables reliable data rates up to ~25 Mbps in point-to-point or party-line bus topologies. |
| Operating Temperature | −55°C to 125°C - Qualified for aerospace, defense, and downhole industrial systems per MIL-PRF-38535. |
| Input Compatibility | TTL-level - Directly interfaces with 74LS/74ALS logic families without level-shifting circuitry. |
| Output Control Logic | Active-low per-channel (C) and global (CC) - Enables selective channel disable for time-multiplexed bus access. |
| Off-State Leakage | ±80 μA max at TA = MAX - Guarantees minimal bus loading during high-impedance state in multi-driver environments. |
Pinout & Package
SN55113J is supplied in a 16-pin Ceramic Dual-In-Line Package (CDIP-J), hermetically sealed for high-reliability military use. Package dimensions: 20.32 mm × 7.62 mm × 4.45 mm (L × W × H), with 2.54 mm lead pitch and SNPB (tin-lead) finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1ZP, 1YP, 2ZP, 2YP | Active Pullup Terminals | Connected internally to VCC via pullup resistors; used with corresponding sink pins (1ZS/1YS/2ZS/2YS) to form differential outputs. |
| 1ZS, 1YS, 2ZS, 2YS | Sink Outputs | Open-collector NPN outputs; sinking current enables AND/NAND logic functions and bus driving capability. |
| 1A, 1B, 2A, 2C, 1C | Data & Control Inputs | 1A/1B feed Channel 1 AND/NAND logic; 2A/2C feed Channel 2; 1C is Channel 1 output enable; CC (Pin 11) is global enable. |
| GND (Pin 8), VCC (Pin 9) | Power Rails | Single 5-V supply operation; ground reference shared across both channels and control logic. |
| CC (Pin 11) | Common Output Control | Active-low global enable: forces all outputs into high-impedance state when asserted, overriding individual controls. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent differential drivers | Enables two simultaneous, isolated RS-422-like signal paths on one IC-reducing board space vs. discrete solutions. |
| Individual + common output controls | Permits fine-grained bus arbitration: e.g., disable only Channel 1 during diagnostics while keeping Channel 2 active. |
| Clamp diodes on all I/O pins | Provides inherent ESD protection (±2 kV HBM) and transient suppression without external TVS devices. |
| High-current sink/pullup outputs | Delivers 40 mA per sink leg with <0.4 V VOL at full load-ensuring robust noise margin in noisy industrial buses. |
| Military temperature qualification | Validated across −55°C to 125°C with full parametric testing-eliminates derating calculations for harsh-environment designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual differential line driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN75113N | Commercial temperature range (0°C to 70°C); PDIP package; RoHS-compliant NiPdAu finish. | Limited to benign environments (e.g., lab equipment, non-mission-critical industrial PLCs). | Select SN75113N only if operating temperature stays within 0–70°C and hermetic sealing is unnecessary. |
| SNJ55113FK | LCCC-20 ceramic package; same military temp range; higher power dissipation (1375 mW @ 25°C) than SN55113J (1375 mW). | Better thermal performance in conduction-cooled modules; requires different PCB footprint and reflow profile. | Choose SNJ55113FK when board layout allows 20-pin LCCC and enhanced thermal management is required. |
Compared with SN75113N, SN55113J offers extended temperature resilience and hermetic reliability for mission-critical systems; compared with SNJ55113FK, it uses a proven 16-pin CDIP footprint with identical electrical specs but lower assembly complexity.

FAQ
What is the maximum operating temperature for SN55113J?
The SN55113J is fully characterized and guaranteed to operate from −55°C to 125°C. This military-grade temperature range is validated per MIL-PRF-38535 requirements, with all electrical parameters tested at both extremes and intermediate points. The SN55113J maintains ±40 mA output drive and <20 ns propagation delay across this full range, making it suitable for engine bay, avionics, and downhole applications where ambient temperatures exceed commercial limits.
Does SN55113J require external pullup resistors?
No, SN55113J does not require external pullup resistors. Its internal architecture provides dedicated active pullup terminals (1YP, 1ZP, 2YP, 2ZP) connected to VCC through integrated resistors (~1 kΩ nominal), which-when paired with corresponding sink outputs (1YS, 1ZS, 2YS, 2ZS)-form complete differential driver stages. External pullups would conflict with this design and degrade noise immunity or increase power consumption.
Can SN55113J be used with SN75115 receivers?
SN55113J is explicitly designed for interoperability with SN55115 (military-grade) receivers, not SN75115. While SN75115 operates over 0°C to 70°C and shares functional compatibility, its input thresholds and common-mode range differ slightly. For guaranteed performance across −55°C to 125°C, TI specifies pairing SN55113J only with SN55115. Using SN75115 may result in marginal timing or noise margin at temperature extremes.
What is the purpose of the CC pin on SN55113J?
The CC (Common Control) pin on SN55113J is an active-low global output enable that forces both driver channels into high-impedance state regardless of individual C-input states. When CC is low, all sink outputs (1YS, 1ZS, 2YS, 2ZS) and pullup terminals become inactive, electrically isolating the device from the bus. This feature is essential for party-line arbitration, system reset sequencing, and fault containment in multi-node differential buses.
Is SN55113J RoHS compliant?
SN55113J is not RoHS compliant-it uses a tin-lead (SNPB) lead finish and is manufactured in a non-RoHS-compliant process flow, consistent with its QML-38535 military qualification. TI offers RoHS-compliant alternatives such as SN75113NSR (SOP-16), but those lack the −55°C to 125°C rating and hermetic packaging. Customers requiring RoHS compliance must evaluate trade-offs in temperature range, reliability, and package type before substituting.
