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.
