Overview
The SN75173D is a monolithic quadruple differential line receiver produced by Texas Instruments. Although this product is no longer in production, it was designed to meet or exceed the requirements of several industry standards, including TIA/EIA-422-B, TIA/EIA-423-B, TIA/EIA-485-A, and ITU recommendations V.10, V.11, X.26, and X.27. The device is optimized for balanced multipoint bus transmission on long bus lines in noisy environments and features 3-state outputs for enhanced flexibility.
