The SN75C1167 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date. Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. All voltage values except differential input voltage are with respect to the network GND.
2. Differential input voltage is measured at the noninverting terminal with respect to the inverting terminal.
