DescriptionThe SN75C1167 and SN75C1168 dual driversand receivers are monolithic integrated circuits designed for balanced transmission lines. The devices meet TIA/EIA-422-B and ITU recommendation V.11.
The SN75C1167 SN75C1168 combines dual 3-state differential line drivers and 3-state differential line receivers, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, which can be connected externally together to function as direction control. The SN75C1168 drivers have individual active-high enables.
The SN75C1167 and SN75C1168 are characterized for operation from 0°C to 70°C.
