QUADRUPLE 2-INPUT POSITIVE-NOR BUFFERS WITH OPEN-COLLECTOR OUTPUTS
These devices contain four independent 2-input NOR buffer gates with open-collector outputs. Open-collector outputs require resistive pull-up to perform logically but can deliver higher VOH levels and are commonly used in wired-AND applications. The SN5433 and SN54LS33 are characterized for operation over the full military temperature range of -55C to 125C. The SN7433, and SN74LS33 are characterized for operation from 0C to 70C.
