DS34LV87TMX

Overview

The DS34LV87TMX/NOPB is an enhanced CMOS quad differential line driver compliant with TIA/EIA-422-B and ITU-T V.11 standards. It operates on a single 3.0V to 3.6V supply, featuring a maximum static current of 100 μA. The device provides four independent drivers with TRI-STATE capability controlled by dual enable inputs. Key electrical parameters include a minimum output differential voltage (VOD) of 2V under load and a maximum propagation delay of 16 ns. It supports data rates up to 30 Mb/s and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Compliant with RS-422 and ITU-T V.11 standards for interoperability with existing 5V networks
• Low power design with TRI-STATE enable functionality to minimize static current consumption
• Enhanced ESD protection exceeding 7 kV on cable I/O pins
• Balanced output crossover characteristics to reduce electromagnetic interference

Applications

• Battery-powered communication systems requiring low quiescent current
• Industrial control networks utilizing RS-422 differential signaling
• High-speed data transmission links operating at frequencies up to 30 Mb/s

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and environmental compliance. Ensure the component status matches project requirements, as certain variants may be designated as lifetime buy or obsolete. Cross-reference the datasheet revision date to validate that all electrical specifications align with current production standards before finalizing procurement orders.

Selection Notes

Select this component when designing systems requiring RS-422 compatibility with reduced power consumption compared to standard 5V drivers. Verify that the 3.3V logic levels are compatible with the host system's input thresholds. Consider the SOIC-16 package dimensions for PCB layout constraints and ensure adequate thermal management for the specified operating temperature range.

Part Context

This part belongs to the DS34LV87T series of enhanced CMOS differential line drivers manufactured by Texas Instruments. It serves as a low-power alternative to legacy 5V RS-422 drivers while maintaining pin compatibility with related devices like the DS26C31. The 'TMX' suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Direct replacements include the DS34LV87TM/NOPB in tube packaging. For similar functionality, verify compatibility with other RS-422 quad drivers from the same family, ensuring voltage levels and pin configurations match.
