SN75ALS173
SN75ALS173 is QUADRUPLE DIFFERENTIAL LINE RECEIVER manufactured by Texas Instruments.
description
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 remendations. Advanced low-power Schottky technology provides high speed without the usual power penalty. The four receivers have an ORed pair of enables in mon. 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 m V over a mon-mode input voltage range of
- 12 V to 12 V.
The SN75ALS173 is characterized for operation from 0°C to 70°C.
