Quadruple Differential Line Receiver

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.
