Description
AI
The SN65ALS1176 differential bus transceiver is designed for bidirectional data communication on multipoint bus transmission lines. The device is designed for balanced transmission lines and meets TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendations V.11 and X.27.
The SN65ALS1176 combines 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 the device an excellent choice for party-line applications.
The SN65ALS1176 is characterized for operation from – 25°C to 85°C.
