Overview
The SN75LBC176ADRG4, produced by Texas Instruments, is a monolithic, integrated circuit designed for bidirectional data communication on multipoint bus-transmission lines. This device is part of the SN75LBC176A series, which is compatible with ANSI standard TIA/EIA-485-A and ISO 8482:1987(E). It combines a 3-state, differential line driver and a differential input line receiver, both operating from a single 5-V power supply. The SN75LBC176ADRG4 is optimized for balanced transmission lines and is suitable for applications requiring robust and reliable data transmission in noisy environments.
