SN65ALS180, SN75ALS180 DIFFERENTIAL DRIVER AND RECEIVER PAIRS SLLS052G – AUGUST 1987 – REVISED APRIL 2003 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.
