The SN65175DR from Texas Instruments is a quad differential line receiver designed for high-speed data communication in industrial and telecom applications. Packaged in a 16-SOIC surface-mount form factor, this IC operates within a 4.75V to 5.25V supply range, making it compatible with standard RS422, RS423, and RS485 protocols. As a receiver-only device (0 drivers/4 receivers), it excels in environments requiring robust noise immunity, featuring 50 mV of receiver hysteresis to enhance signal integrity in electrically noisy conditions. With RoHS3 compliance and REACH unaffected status, it meets stringent environmental regulations while offering reliable performance in harsh operating conditions.
The SN65175DR stands out as a high-performance differential line receiver, combining robust noise immunity, protocol flexibility, and industrial-grade reliability. Its obsolete status may limit new designs, but it remains a proven solution for legacy systems requiring stable, noise-resistant communication. Engineers seeking a 5V-compatible, hysteresis-enhanced receiver for harsh environments will find this IC a dependable choice, particularly in industrial, telecom, and medical applications. For new projects, consider Texas Instruments' active alternatives with similar or enhanced features.
