DS1487M/NOPB TI RS-485 Transceiver | 8-SOIC | 5V, 250kbps, Half-Duplex

Product Overview

The DS1487M/NOPB is a low-power, differential bus/line transceiver designed by Texas Instruments for RS-485 and RS-422 communication. It operates from a single 5V supply and features a half-duplex configuration with a driver and receiver on a single chip. The device is housed in an 8-pin SOIC package, making it suitable for space-constrained applications. With a data rate of up to 250 kbps and a wide common-mode range, it ensures reliable data transmission over long distances in noisy industrial environments.
