description/ordering information (continued)

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, that can be connected together externally to function as a direction control.

The driver differential outputs and the receiver differential inputs are connected to separate terminals for greater

These ports feature wide positive and negative common-mode voltage ranges, making the device suitable for

party-line applications.
