Overview
The SN75LBC176DR, produced by Texas Instruments, is a differential bus transceiver designed for bidirectional data communication on multipoint bus-transmission lines. This integrated circuit meets or exceeds the requirements of ANSI Standard TIA/EIA-485-A and ISO 8482:1987(E), making it suitable for RS-485 and RS-422 applications. The device combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5-V power supply. It features active-high and active-low enables for the driver and receiver, respectively, which can be externally connected to function as a direction control.
