DS34LV86TMX/NOPB

Overview

The DS34LV86TMX/NOPB is a high-speed quad differential CMOS receiver manufactured by Texas Instruments. It complies with TIA/EIA-422-B and ITU-T V.11 standards for RS-422 communication. The device operates on a single 3.3V power supply, with a voltage range of 3V to 3.6V. It supports data rates up to 30 Mb/s and features a typical quiescent current of 9 mA. The component includes an open-input failsafe feature that ensures a high output state when inputs are disconnected. It provides a common mode range of ±7V at VID = 3V and ±10V at VID = 0.2V. The unit is housed in a 16-pin SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Enhanced CMOS design optimized for low power consumption in battery-operated systems
• Integrated open-input failsafe mechanism to maintain signal integrity during disconnection
• Tri-state outputs allow flexible bus management and power reduction when disabled

Applications

• RS-422 serial communication networks
• Industrial control systems requiring robust differential signaling
• Data acquisition equipment operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'TMX' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official manufacturer documentation as regulatory requirements may vary by production batch. Ensure the ordering part number matches the exact pinout and electrical specifications required for the target circuit design before finalizing procurement.

Selection Notes

Select this component when interfacing with existing 5V RS-422 networks using 3.3V logic supplies. It serves as a direct pin-compatible replacement for the DS34C86T series while offering improved power efficiency. Consider the wide common mode voltage range for applications involving long cable runs or significant ground potential differences between transmitter and receiver nodes.

Part Context

This device belongs to the DS34LV86T family of enhanced CMOS receivers designed for reliable data transmission. It complements other interface solutions like the DS34LV87 driver series within the same product ecosystem. The component addresses the need for high-speed, low-power differential reception in modern electronic systems where signal integrity is critical.

Replacement Considerations

DS34LV86TM/NOPB is confirmed as a direct substitute offering identical functionality in tube packaging.
