DESCRIPTION

The UT54ACS4002 and the UT54ACTS4002 are dual 4-input

NOR gates. A high on any input forces the output to a low state.

The circuits perform the Boolean functions:

Y = A + B + C + D = A

⋅B⋅C⋅D.

The devices are characterized over full military temperature

range of -55

°C to +125°C.
