Military 4-ch, 2-input, 4.5-V to 5.5-V bipolar NOR gates with open-collector outputs

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.
