说明

The SN75ALS173 is a monolithic quadruple differential line receiver with 3-state outputs. It is designed to meet the requirements of ANSI Standards EIA/TIA-422-B, EIA/TIA-423-B, RS-485, and several ITU recommendations. Advanced low-power Schottky technology provides high speed without the usual power penalty. The four receivers have an ORed pair of enables in common. Either G high or G\ low enables all of the receivers. The device features high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ±200 mV over a common-mode input voltage range of -12 V to 12 V.

The SN75ALS173 is characterized for operation from 0°C to 70°C.

H = high level, L = low level, ? = indeterminate,
X = irrelevant, Z = high impedance (off)
