DESCRIPTION
The UT54ACS132 and the UT54ACTS132 are 2-input NAND
gates with Schmitt Trigger input levels. A high applied on both
the inputs forces the output to a low state.
The devices are characterized over full military temperature
range of -55 C to +125 C.

Note:
1. Stresses outside the listed absolute maximum ratings may cause permanent damage to the device. This is a stress rating only, functional operation of the device
at these or any other conditions beyond limits indicated in the operational sections is not recommended. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
