Product Description

The SN75ALS1178NSR is a dual Differential Driver and Receiver integrated circuits designed for bidirectional data communication on multipoint bus transmission lines. It is designed for balanced transmission lines and meets standards TIA/EIA-422-B and TIA/EIA-485-A. It combines dual 3-state differential line drivers and dual 3-state differential input line receivers, both of which operate from a single 5V power supply. The driver and receiver has active-high and active-low enables, respectively, which can be externally connected together to function as direction control. The driver each has an individual active-high enable. Failsafe design ensures that when the receiver inputs are open, the receiver outputs are always high.
