SN74HC7002D Description

The SN74HC7002D from Texas Instruments is a high-performance quad 2-input NOR gate IC in the 74HC series, designed for surface-mount applications (14-SOIC package). Operating within a 2V to 6V supply range, it delivers a maximum propagation delay of 22ns at 6V with a 50pF load, ensuring reliable high-speed logic operations. This device features Schmitt-trigger inputs, enhancing noise immunity and signal integrity in noisy environments. With low quiescent current (2µA max) and symmetrical output drive (5.2mA sink/source), it is optimized for low-power digital systems. Compliant with ROHS3 and REACH standards, it is suitable for industrial and consumer electronics.
