DS34LV87TM/NOPB

Overview

The DS34LV87TM/NOPB is an enhanced CMOS quad differential line driver manufactured by Texas Instruments, designed for RS-422 communication interfaces. It operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 30 Mb/s. The device features four independent drivers with tri-state outputs and consumes a maximum operating supply current of 100 µA. It is housed in a 16-pin SOIC package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Enhanced CMOS technology provides low power consumption suitable for battery-operated systems
• Supports high-speed data transmission up to 30 Mb/s for reliable RS-422 communication
• Integrated tri-state outputs allow multiple drivers to share bus lines without interference

Applications

• RS-422 serial communication networks
• Industrial control systems requiring differential signaling
• Data acquisition systems with long-distance transmission needs

Procurement Notes

Verify the component authenticity through authorized Texas Instruments distributors or certified suppliers. Confirm the presence of the NOPB suffix indicates lead-free and RoHS compliance. Ensure the SOIC-16 package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when designing RS-422 interfaces requiring low voltage operation between 3.0 V and 3.6 V. It is appropriate for applications needing four differential drivers with high data rate capabilities up to 30 Mb/s. Consider the 100 µA quiescent current for power-sensitive designs compared to standard 5V counterparts.

Part Context

This part belongs to the DS34LV87T series of enhanced CMOS quad differential line drivers. It serves as a low-voltage alternative to standard 5V RS-422 drivers, offering improved power efficiency while maintaining compatibility with RS-422 electrical standards for robust noise immunity in differential signaling applications.

Replacement Considerations

DS34LV87TMX/NOPB is available in tape-and-reel packaging as a functional equivalent.
