RS-485 и RS-422 SN75ALS176D

Приемопередатчик , 4.75В до 5.25В, SOIC-8

The SN75ALS176D is a Differential Bus Transceiver designed for bidirectional data communication on multipoint bus transmission lines. It is also designed for balanced transmission lines and meets TIA/EIA-422-B, TIA/EIA-485-A and ITU Recommendations V.11 and X.27. The SN75ALS176 series combine a 3-state, differential line driver and a differential input line receiver, which operate from a single 5V power supply. The driver and receiver have active-high and active-low enables, 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 the device suitable for party-line applications.
