It packages four independent NOR gates in a 14-pin DIP (0.300\" body) for through-hole assembly. Each gate accepts two inputs and delivers a NOR output, with a propagation delay of 15 ns at 6 V driving a 50 pF load. The supply range spans 2 V to 6 V. Output sink and source capability is 5.2 mA per gate. ## Military temperature grade — deployment context The -55°C to 125°C operating temperature range qualifies this part for military, aerospace, and downhole instrumentation. The 14-DIP package is socket-friendly, easing field replacement during board rework or prototype iteration. ## Sourcing and lifecycle It is ROHS3 compliant (cites). No official second-source alternate is listed in the record, but the 74HC family is broadly second-sourced by multiple manufacturers; a pin-compatible NOR gate from another vendor can be qualified for dual-sourcing if needed.","metaTitle":"CD74HC02E NOR Gate, 15ns @ 6V, 14-DIP, Active","metaDescription":"CD74HC02E quad 2-input NOR gate, 2V-6V supply, 15ns delay, -55°C to 125°C, 14-DIP.
