description

These devices contain three independent 3-input

NAND gates with open-collector outputs. These

gates perform the Boolean functions Y = A•B•C or

Y = A+B+C in positive logic. The open-collector

outputs require pullup resistors to perform

correctly. They may be connected to other

open-collector outputs to implement active-low

wired-OR or active-high wired-AND functions.

Open-collector devices are often used to generate

The SN54ALS12A is characterized for operation

over the full military temperature range of −55°C

to 125°C. The SN74ALS12A is characterized for

operation from 0°C to 70°C.
