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

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.
