SN75176BP

SN75176BP is a differential bus transceiver designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and meets ANSI standards TIA/EIA-422-B and TIA/EIA-485-A and ITU recommendations V.11 and X.27. The SN75176B device combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5V 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. Applications include chemical and gas sensors, digital signage, HMI (human-machine interfaces), motor controls: AC induction, brushed and brushless dc, low- and high-voltage, stepper motors, and permanent magnets, TETRA base stations, telecom towers: remote electrical tilt units (ret) and tower mounted amplifiers (TMA), weigh scales, wireless repeaters.
