SN65LBC174ADW Description

The SN65LBC174ADW from Texas Instruments is a high-performance quad differential line driver designed for RS-422 and RS-485 communication systems. Housed in a 20-pin SOIC package, this surface-mount IC operates within a 4.75V to 5.25V supply range, ensuring compatibility with standard 5V logic systems. With a data rate of 30Mbps, it supports high-speed data transmission, making it ideal for industrial and telecom applications. The device features 40mV of receiver hysteresis, enhancing noise immunity in electrically noisy environments. As a 4/0 (4 drivers, 0 receivers) configuration, it is optimized for unidirectional communication, reducing complexity in systems where bidirectional transceivers are unnecessary.
