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.
There is no NRND or last-time-buy notice.
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.
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.
