SN65176BDR | Texas Instruments

Bus Transceiver, SN65176BDR, Texas Instruments

The SN65176BDR differential bus transceiver is designed for bidirectional data communication on multipoint bus transmission lines. It is optimized for balanced transmission lines and meets ANSI Standards TIA/EIA-422-B and TIA/EIA-485-A, as well as ITU Recommendations V.11 and X.27. The SN65176BDR combines a 3-state differential line driver and a differential input line receiver, both operating from a single 5 V power supply. The driver has an active-high enable, and the receiver has an active-low enable, which can be connected together externally to function as a direction control. The driver differential outputs and receiver differential inputs are connected internally to form differential input/output (I/O) bus ports, designed to offer minimal loading to the bus when the driver is disabled or V_CC = 0. These ports feature wide positive and negative common-mode voltage ranges, making the SN65176B suitable for party-line applications.
