SN74ALS33A buffers equivalent, quadruple 2-input positive-nor buffers.
These devices perform the Boolean functions Y = A
* B or Y = A + B in positive logic.
The SN54ALS33A is characteriz.
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..
