Description

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 VOHlevels and are commonly used in wired-AND applications. The SN5433 and SN54LS33 are characterized for operation over the full military temperature range of -55°C to 125°C. The SN7433, and SN74LS33 are characterized for operation from 0°C to 70°C.
