description

These devices contain four independent 2-input

positive-NOR buffers with open-collector outputs.

Open-collector outputs require resistive pullup to

perform correctly. They can deliver higher VOH

levels and commonly are used in wired-AND

applications. These devices perform the Boolean

functions Y = A • B or Y = A + B in positive logic.

The SN54ALS33A is characterized for operation

over the full military temperature range of −55°C

to 125°C. The SN74ALS33A is characterized for

operation from 0°C to 70°C.
