description

The SN65ALS176 and SN75ALS176 series differential bus transceivers are monolithic integrated circuits designed for bidirectional data communication on multipoint bus transmission lines. They are designed for balanced transmission lines and meet ANSI Standards EIA/TIA-422-B and RS-485 and ITU Recommendations V.11 and X.27.

The SN65ALS176 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, which can be externally connected together 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 whenever the driver is disabled or V_CC = 0. This port features wide positive and negative common-mode voltage ranges making the device suitable for party-line applications.

The SN65ALS176 is characterized for operation from -40°C to 85°C, and the SN75ALS176 series is characterized for operation from 0°C to 70°C.
