DS34LV86TMX

Overview

The DS34LV86TMX/NOPB is a high-speed quad differential CMOS line receiver manufactured by Texas Instruments. It operates on a single 3.0V to 3.6V supply voltage with a typical static current of 9 mA. The device meets TIA/EIA-422-B and ITU-T V.11 standards, supporting data rates up to 32 MHz toggle frequency. It features a ±7V common mode range at VID = 3V and ±10V at VID = 0.2V. The receiver includes an open input failsafe feature ensuring a High output when inputs are left open. Propagation delay ranges from 6 ns to 35 ns with a maximum skew of 4 ns. It provides >6.5 kV ESD tolerance (HBM) and is available in a 16-pin SOIC package.

Feature Summary

• Low power CMOS design suitable for battery-powered applications
• Interoperable with existing 5V RS-422 networks
• Receiver OPEN input failsafe feature ensures High output state
• Pin compatible with DS34C86T

Applications

• Industrial communication systems requiring RS-422 compliance
• Battery-powered devices needing low static current consumption
• High-speed data transmission lines operating up to 32 MHz

Procurement Notes

Verify the specific ordering suffix to confirm RoHS compliance and lead finish. The 'NOPB' suffix indicates a lead-free and halogen-free product. Confirm the package type matches the required PCB footprint, typically SOIC-16. Check the latest datasheet revision for any updates to absolute maximum ratings or recommended operating conditions before finalizing procurement specifications.

Selection Notes

Select this component when interfacing with standard RS-422 networks while requiring lower power consumption than bipolar alternatives. Ensure the application environment stays within the -40°C to +85°C industrial temperature range. Verify that the signal levels fall within the specified common mode voltage limits. Consider the pin compatibility with DS34C86T if upgrading from older designs without changing the board layout.

Part Context

This part belongs to the DS34LV86T family of enhanced CMOS quad differential line receivers. It serves as a low-power alternative to traditional bipolar receivers like the DS34C86T. The device is designed to maintain interoperability with legacy 5V RS-422 infrastructure while offering improved power efficiency for modern 3.3V logic systems.

Replacement Considerations

DS34LV86TM/NOPB is a direct pin-compatible replacement for the discontinued DS34LV86TM.
