75176BD

SN75176BD Differential Bus Transceiver IC

The SN75176BD is a high-performance differential bus transceiver from Texas Instruments, engineered for reliable bidirectional data communication on multipoint bus transmission lines. Fully compliant with ANSI standards TIA/EIA-422-B and TIA/EIA-485-A as well as ITU Recommendations V.11 and X.27, this component is an excellent choice for game room equipment repair and restoration projects — including pinball machines, arcade cabinets, and other coin-operated equipment that rely on robust serial communication between control boards. Operating from a single 5V supply, the SN75176BD combines a 3-state differential line driver and a differential input line receiver, making it a versatile and dependable solution for noisy, long-bus-line environments common in arcade and pinball electronics.

Built with protective features like thermal shutdown at approximately 150°C and positive/negative current limiting, the SN75176BD is designed to withstand demanding conditions. Its wide common-mode voltage range makes it ideal for party-line applications, while the high-impedance bus ports minimize loading when the driver is disabled.
