The SN75ALS176B and SN75ALS176 series differential bus transceivers are designed for bidirectional data communication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27.
The SN75ALS176B and SN75ALS176 series combine a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be connected together externally to function as a direction control.
The driver differential outputs and the receiver differential inputs are connected internally to form a differential input/output (I/O) bus port that is designed to offer minimum loading to the bus when the driver is disabled or VCC = 0. This port features wide positive and negative common-mode voltage ranges, making SN75ALS176B suitable for party-line applications.
The SN75ALS176B is characterized for operation from 40°C to 85°C, and the SN75ALS176 series is characterized for operation from 0°C to 70°C.
