Product details
Overview
DS34LV86TM/NOPB from Texas Instruments is a 3.3V quad differential line receiver compliant with TIA/EIA-422-B and ITU-T V.11 standards, featuring ±10V common-mode range at 0.2V input threshold, 32 MHz toggle frequency, and TTL/LVCMOS-compatible outputs. It serves as the signal-receiving stage in industrial RS-422 communication links, enabling robust data recovery in noisy factory-floor or motor-control environments.
For engineers reviewing the DS34LV86TM/NOPB datasheet, DS34LV86TM/NOPB pinout, DS34LV86TM/NOPB application, or DS34LV86TM/NOPB equivalent, key selection criteria include failsafe open-input behavior, dual enable control for power-gated channel management, low 9 mA typical ICC, and SOIC-16 package compatibility with legacy DS34C86T layouts.
Technical Context
The DS34LV86TM/NOPB implements four independent CMOS receivers with differential input pairs (RI+, RI−) and active-high enable inputs (EN), each driving a TTL/LVCMOS-compatible output (RO). Its failsafe logic ensures RO = High when inputs are open or unterminated - critical for bus idle-state detection in point-to-point or multidrop RS-422 systems.
Each receiver supports wide common-mode voltage operation (±10V at VID ≤ ±0.2V), operates from 3.0–3.6V supply, and delivers sub-35 ns propagation delay with ≤4 ns skew between channels. The dual enable scheme allows per-channel or group-wise disable to reduce static current to near-zero during standby.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 3.0–3.6 V - Enables direct integration into 3.3V system rails without level-shifting. |
| Common-Mode Range | ±10 V @ VID ≤ ±0.2 V - Supports long cable runs and ground-potential differences in industrial machinery. |
| Input Threshold | ±200 mV - Ensures reliable detection of low-amplitude differential signals under noise. |
| Max Toggle Frequency | 32 MHz - Supports high-speed serial links up to 16 MBaud in full-duplex RS-422 configurations. |
| Propagation Delay | 6–35 ns - Guarantees timing predictability in synchronous data acquisition and motion-control feedback loops. |
| Receiver Skew | ≤4 ns (max part-to-part) - Maintains channel alignment across multi-axis encoder or sensor interfaces. |
| ESD Rating (HBM) | ≥6.5 kV on inputs/enables - Reduces need for external TVS protection in panel-mounted I/O modules. |
Pinout & Package
DS34LV86TM/NOPB uses a 16-pin SOIC (Package D) with 1.27 mm pitch, 10.3 mm × 6.5 mm body size, and RoHS-compliant matte tin (SN) lead finish. Pin 1 is marked with a notch or dot; device is MSL Level-1 rated for unlimited floor life at ≤30°C/60% RH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 7, 10 | RI+ (Receiver Input +) | Differential positive input for Channels A–D; accepts ±14V absolute max input voltage. |
| 2, 5, 8, 11 | RI− (Receiver Input −) | Differential negative input for Channels A–D; referenced to same common-mode range as RI+. |
| 3, 6, 9, 12 | EN (Enable) | Active-high enable per channel; drives RO to high-impedance state when low. |
| 13, 14, 15, 16 | RO (Receiver Output) | TTL/LVCMOS-compatible digital output; sinks 6 mA / sources 100 µA minimum. |
| 16 | VCC | 3.3V supply pin; requires local 0.1 µF + 0.01 µF ceramic decoupling per TI recommendations. |
| 8 | GND | Ground reference for all inputs, outputs, and supply; shared return path for all four channels. |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe open-input detection | RO asserts High when RI+/RI− are unconnected or unterminated - prevents undefined logic states during cable disconnect or driver fault. |
| Dual enable architecture | Four independent EN pins allow selective channel shutdown - reduces dynamic power by >90% per disabled channel in partial-link applications. |
| Wide common-mode tolerance | ±10V input range at low VID enables use with non-isolated transceivers across 100+ meter twisted-pair runs with ground offsets. |
| Low static current | 9 mA typical ICC at VCC = 3.3V and all inputs open - extends battery life in portable HMI or field instrument designs. |
| Pin compatibility with DS34C86T | Direct drop-in replacement for legacy 5V RS-422 receivers when migrating to 3.3V systems - no PCB redesign required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad RS-422 receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3095CSA+ | 5V-only supply; ±15V common-mode range; no failsafe open-input feature. | Suitable for legacy 5V systems but requires external pull-up/pull-down for idle-state logic definition. | Select when interfacing with older 5V RS-422 drivers and board space permits external biasing components. |
| SN65LBC184DR | Integrated transient suppression; 3.3V/5V dual-supply support; single-channel per package. | Requires four devices for quad functionality; higher cost per channel but superior surge immunity per IEC 61000-4-5. | Prefer when operating in outdoor or utility-grade installations subject to lightning-induced surges. |
Compared with MAX3095CSA+ and SN65LBC184DR, the DS34LV86TM/NOPB offers optimal balance of 3.3V efficiency, built-in failsafe behavior, and pin-compatible upgrade path from DS34C86T - making it ideal for cost-sensitive industrial upgrades where PCB reuse is mandatory.

FAQ
What is the maximum common-mode voltage the DS34LV86TM/NOPB can tolerate while maintaining valid output logic?
The DS34LV86TM/NOPB guarantees correct operation with a common-mode input voltage range of ±10V when the differential input voltage (VID) is ≤ ±0.2V. This specification is validated across the full −40°C to +85°C temperature range and ensures reliable signal recovery even with large ground potential differences between transmitter and receiver nodes. The DS34LV86TM/NOPB maintains this rating without external biasing or termination adjustments.
Does the DS34LV86TM/NOPB require external pull-up or pull-down resistors on its inputs to ensure defined logic states?
No - the DS34LV86TM/NOPB features an integrated open-input failsafe circuit that forces each RO output to logic High when its corresponding RI+/RI− pair is left unconnected or unterminated. This eliminates the need for external biasing resistors in idle-bus or hot-swap scenarios, simplifying PCB layout and improving system reliability during cable disconnect events. The DS34LV86TM/NOPB implements this behavior internally using precision threshold comparators.
Can the DS34LV86TM/NOPB be used with 5V RS-422 drivers without level shifting?
Yes - the DS34LV86TM/NOPB is interoperable with existing 5V RS-422 networks due to its ±14V absolute maximum input voltage rating and compliance with TIA/EIA-422-B electrical specifications. Its input thresholds (±200 mV) and common-mode tolerance (±10V) align with 5V driver output levels, allowing direct connection without level translators. The DS34LV86TM/NOPB achieves this while operating from a 3.3V supply, reducing system power consumption versus legacy 5V receivers.
How does the dual enable architecture of the DS34LV86TM/NOPB improve power efficiency in partial-link applications?
The DS34LV86TM/NOPB provides four independent EN pins - one per receiver channel - enabling selective shutdown of unused channels while keeping others active. When EN is low, the corresponding RO enters high-impedance state and ICC drops to <1 µA, reducing total supply current proportionally. In a 4-channel system using only two links, disabling two channels cuts static power by ~50%. This granular control is implemented directly in the DS34LV86TM/NOPB silicon without external logic.
Is the DS34LV86TM/NOPB pin-compatible with the older DS34C86T, and what design changes are needed for migration?
Yes - the DS34LV86TM/NOPB is explicitly documented as pin-compatible with the DS34C86T, sharing identical SOIC-16 pinout, terminal functions, and footprint. Migration requires only a supply voltage change from 5V to 3.3V and removal of any input biasing previously needed for DS34C86T's lack of failsafe behavior. No PCB layout modification is necessary, and the DS34LV86TM/NOPB retains full functional equivalence while delivering lower power and enhanced robustness.
