Part identity and key parametrics
The CD74HC4002M is a dual 4-input NOR gate from the 74HC high-speed CMOS logic family, operating across a 2V to 6V supply range. Each of the two independent NOR gates accepts four inputs, with output drive capability of 5.2 mA for both sourcing and sinking. The quiescent current max is 2 µA, keeping the static power draw negligible in battery-powered or always-on circuits.
It can be deployed in engine-bay electronics, outdoor telecom, or downhole instrumentation without derating the logic family. The input logic thresholds are specified as 0.5V to 1.8V for low level and 1.5V to 4.2V for high level across the supply range, ensuring compatibility with both 3.3V and 5V CMOS logic without external level translation in most cases.
Supplied in a 14-SOIC (0.154", 3.90mm width) surface-mount package, the CD74HC4002M mounts directly on standard 1.27 mm pitch SOIC footprints. The supplier device package is 14-SOIC; the tube packaging means parts arrive in anti-static tubes, suitable for pick-and-place or hand assembly. Surface-mount assembly keeps the board profile low, and the SOIC-14 body is compatible with most reflow profiles. No special thermal pad or exposed paddle is required.
