Product details

What this part is and where it fits

The Texas Instruments CD74HC4002PWR is a dual 4-input NOR gate from the 74HC high-speed CMOS logic family. It packages two independent NOR circuits, each with four inputs, in a 14-TSSOP surface-mount package. The part operates across a 2V to 6V supply range and draws a maximum quiescent current of 2 µA, making it suitable for battery-powered and low-power logic designs. With a full military temperature range of -55°C to 125°C, it is rated for avionics, satellite, downhole, and other harsh-environment applications where commercial or industrial parts would not survive.

Lifecycle and sourcing

The CD74HC4002PWR is listed as Active with ROHS3 compliance. There is no NRND or last-time-buy notice.

Frequently asked questions

What is the pinout of CD74HC4002PWR?

The pinout follows the standard 14-TSSOP NOR gate layout: two independent 4-input NOR gates with common VCC and GND. Pin 1 is marked by a dot on the package. Refer to the Texas Instruments datasheet for the full pin assignment diagram.

What is the equivalent or replacement for CD74HC4002PWR?

A direct functional equivalent is the SN74HC21DR from Texas Instruments, which is a dual 4-input AND gate in the same 74HC family and 14-TSSOP package. For a NOR gate specifically, there is no pin-for-pin second source listed; the CD74HC4002PWR is the primary active part for this logic function.
