Product details
Overview
DS34LV86TMX/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 a high-speed interface receiver in industrial serial communication links requiring robust noise immunity and low-power operation.
For engineers reviewing the DS34LV86TMX/NOPB datasheet, DS34LV86TMX/NOPB pinout, DS34LV86TMX/NOPB application, or DS34LV86TMX/NOPB equivalent, key selection criteria include receiver skew (≤4 ns), failsafe open-input behavior, tri-state enable control, and SOIC-16 packaging for RS-422 signal integrity in harsh environments.
Technical Context
The DS34LV86TMX/NOPB implements four independent CMOS receivers with dual enable inputs per channel, supporting flexible channel-level power gating. Each receiver features internal hysteresis (35 mV) and guaranteed high output on open inputs, eliminating external biasing in unterminated lines.
It operates across −40°C to +85°C with 3.0–3.6 V supply, draws 9 mA typical ICC under no-load conditions, and delivers 10 ns transition time with ≤4 ns max skew between channels - enabling synchronous multi-channel data recovery in deterministic timing systems.
Key Specifications

| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3V logic rails and tolerant of board-level voltage variation |
| Common-Mode Range | ±10 V at VID = 0.2 V - supports long cable runs with ground potential differences up to 20 V |
| Input Threshold | ±200 mV differential - ensures reliable detection of low-amplitude signals over full common-mode range |
| Max Toggle Frequency | 32 MHz - enables reception of high-speed serial data streams such as industrial encoder feedback or fieldbus protocols |
| Propagation Skew | ≤4 ns (max) - guarantees tight timing alignment across all four receivers for parallel bus reconstruction |
| ESD Rating | ≥6.5 kV HBM on receiver inputs - provides robust protection against electrostatic discharge during handling and system integration |
| Operating Temperature | −40°C to +85°C - qualified for use in industrial automation, motor drives, and outdoor equipment enclosures |
Pinout & Package
DS34LV86TMX/NOPB is housed in a 16-pin SOIC (Package D) with 1.27 mm pitch, JEDEC MS-012AC compliant, and RoHS-compliant matte tin lead finish. The package supports surface-mount reflow per Level-1-260°C specifications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | RI+ (Receiver Input +) | Differential positive input for Channels A–D; accepts ±14 V absolute max, supports failsafe detection when open |
| 2, 5, 11, 14 | RI− (Receiver Input −) | Differential negative input for Channels A–D; paired with RI+ to reject common-mode noise up to ±10 V |
| 3, 6, 12, 15 | RO (Receiver Output) | TTL/LVCMOS-compatible digital output (0.13–3.0 V swing); tri-stated when EN = L |
| 7, 8 | EN (Enable Inputs) | Active-high dual enable controlling Channels A/B (Pin 7) and C/D (Pin 8); allows selective channel activation |
| 16 | VCC | 3.3 V supply pin; requires local 0.1 µF + 0.01 µF ceramic decoupling per TI recommendations |
| 9 | GND | Ground reference for all receiver circuits and enable logic; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Failsafe open-input detection | RO forced high when RI+/RI− are unconnected - eliminates need for external pull-up resistors in point-to-point links |
| Dual independent enable control | Separate EN pins for two receiver pairs - enables dynamic power management in multi-drop or partial-link active configurations |
| Low static power consumption | 9 mA typical ICC at VCC = 3.3 V - reduces thermal load and extends battery life in portable diagnostic tools |
| High ESD tolerance | ≥6.5 kV HBM on RI+/RI−/EN - meets IEC 61000-4-2 Level 3 requirements without external TVS diodes |
| Guaranteed AC timing | 4 ns max skew and 10 ns transition time - ensures setup/hold margin compliance in 32 MHz clocked systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad differential receiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| DS34C86T | 5 V operation only; identical pinout and functional behavior; higher ICC (25 mA typical) | Requires 5 V supply rail; not suitable for mixed-voltage 3.3 V systems | Select DS34C86T only if legacy 5 V infrastructure exists and power budget permits higher dissipation. |
| SN65LVDS32DR | LVDS input standard (not RS-422); 3.3 V only; 16-pin SOIC; no open-input failsafe | Designed for point-to-point LVDS links, not multidrop RS-422 buses; lacks built-in failsafe | Choose SN65LVDS32DR for high-speed point-to-point interconnects where LVDS compliance is required and external biasing is acceptable. |
Compared with DS34C86T and SN65LVDS32DR, the DS34LV86TMX/NOPB uniquely combines 3.3 V operation, RS-422/V.11 compliance, failsafe open-input behavior, and dual enable control - making it the only option among the three qualified for industrial multidrop serial backplanes with variable ground potentials.

FAQ
What is the maximum common-mode voltage range supported by the DS34LV86TMX/NOPB?
The DS34LV86TMX/NOPB supports a ±10 V common-mode range when the differential input voltage (VID) is 0.2 V, and ±7 V when VID is 3 V. This wide range enables reliable operation across large ground potential differences in industrial cabling environments, directly supporting TIA/EIA-422-B and ITU-T V.11 compliance. The DS34LV86TMX/NOPB maintains valid output states throughout this range without external level-shifting circuitry.
Does the DS34LV86TMX/NOPB require external biasing resistors for unterminated lines?
No, the DS34LV86TMX/NOPB includes an integrated open-input failsafe feature that forces the RO output high when RI+ and RI− are left unconnected or unterminated. This eliminates the need for external pull-up/pull-down resistors in point-to-point or stubbed RS-422 configurations. The DS34LV86TMX/NOPB achieves this via internal circuitry referenced to VCC/2, ensuring predictable startup and fault behavior without added BOM cost or layout complexity.
What is the purpose of the dual enable inputs (Pins 7 and 8) on the DS34LV86TMX/NOPB?
Pins 7 and 8 serve as independent active-high enable controls: Pin 7 enables Channels A and B, while Pin 8 enables Channels C and D. This architecture allows selective activation of receiver pairs to reduce dynamic power consumption in partial-link applications - for example, disabling unused channels during low-bandwidth monitoring modes. The DS34LV86TMX/NOPB enters tri-state output mode immediately upon enable deassertion, preventing bus contention in shared backplane designs.
Is the DS34LV86TMX/NOPB pin-compatible with older 5 V receivers?
Yes, the DS34LV86TMX/NOPB is explicitly pin-compatible with the DS34C86T, a 5 V counterpart. Both share identical SOIC-16 pinouts, truth tables, and functional block diagrams. However, the DS34LV86TMX/NOPB operates at 3.3 V and draws significantly less current (9 mA vs. 25 mA typical), so direct substitution requires verification of supply voltage and noise margin compatibility in the target system. The DS34LV86TMX/NOPB retains full interoperability with existing 5 V RS-422 drivers.
What decoupling capacitance is recommended for the DS34LV86TMX/NOPB VCC pin?
Texas Instruments recommends placing a 0.1 µF ceramic capacitor in parallel with a 0.01 µF ceramic capacitor directly at the VCC pin (Pin 16) of the DS34LV86TMX/NOPB, with short traces to GND (Pin 9). Additionally, a bulk 10 µF or greater solid tantalum or electrolytic capacitor should be located near the board's main power entry point. This three-tier decoupling strategy suppresses high-frequency switching noise and maintains stable 3.3 V supply during fast output transitions in the DS34LV86TMX/NOPB.
