The SN65ALS180 and SN75ALS180 differential driver and receiver pairs are monolithic integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. SN65ALS180 and SN75ALS180 are designed for balanced transmission lines and meet TIA/EIA-422-B, TIA/EIA-485-A, and ITU Recommendation V.11.

The SN65ALS180 and SN75ALS180 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, SN65ALS180 and SN75ALS180 can be externally connected together to function as a direction control. The driver differential outputs and the receiver differential inputs are connected to separate terminals for greater flexibility and are designed to offer minimum loading to the bus when the driver is disabled or VCC = 0.

These ports of SN65ALS180 and SN75ALS180 feature wide positive and negative common-mode voltage ranges, making the device suitable for party-line applications.

The SN65ALS180 is characterized for operation from 40°C to 85°C. The SN75ALS180 is characterized for operation from 0°C to 70°C.
