DS3487MX

Drivers, Receivers, Transceivers Overview

The DS3487MX is a quad TRI-STATE line driver manufactured by Texas Instruments, designed for RS-422 communication interfaces. It operates within a supply voltage range of 4.75 V to 5.25 V, with a typical operating voltage of 5 V. The device supports data rates up to 10 Mb/s and features a propagation delay of 10 ns. It draws a maximum operating supply current of 80 mA and dissipates up to 1.051 W of power. The output voltage reaches 2 V, and it functions reliably across an ambient temperature range of 0°C to +70°C. Packaged in a 16-pin SOIC-Narrow (SOIC-N) surface-mount format, this component provides four drivers without integrated receivers or shutdown capabilities.

Drivers, Receivers, Transceivers Feature Summary

• Quad TRI-STATE line driver configuration supporting RS-422 differential signaling standards
• High-speed data transmission capability reaching 10 Mb/s with low propagation delay
• TRI-STATE outputs allow multiple drivers to share transmission lines without interference

Drivers, Receivers, Transceivers Applications

• RS-422 balanced digital interface circuits
• Multi-drop communication bus systems
• Industrial control network nodes requiring differential signaling

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix MX against official datasheets to confirm package type and temperature grade. Confirm end-of-life status as some sources indicate discontinuation. Ensure compatibility with existing PCB footprints for 16-SOIC packages before procurement planning.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver is required for RS-422 applications without receiver integration. Compare against the MC3487 series for industrial temperature variants if operation below 0°C is needed. Verify that the absence of a shutdown pin aligns with system power management requirements.

Drivers, Receivers, Transceivers Part Context

The DS3487MX belongs to the DS3487 family of RS-422 interface ICs from Texas Instruments. It serves as a high-speed transmitter counterpart to receiver components like the DS3486. The part is distinct from the MC3487 series, which typically offers extended temperature ranges for industrial environments.
