CD4002BPW

CD4002BPW Description

The CD4002BPW from Texas Instruments is a dual 4-input NOR gate IC belonging to the 4000B series, designed for high-reliability logic operations. Packaged in a 14-pin TSSOP (Tube), it operates across a wide 3V to 18V supply range, making it versatile for both low-power and industrial applications. With a max propagation delay of 90ns @ 15V, 50pF, it ensures stable performance in medium-speed digital circuits. The device features low quiescent current (1 µA max), making it energy-efficient, and supports 3.4mA output current for driving moderate loads. Its RoHS3 compliance and REACH-unaffected status ensure environmental and regulatory adherence.
