CD4002BE CMOS Dual 4-Input NOR Gate Breadboard-Friendly (Pack of 10)

Description

Product Overview

The TI CD4002BE is a CMOS dual 4‑input NOR gate that delivers consistent logic performance for a wide range of electronic projects. Each package contains ten identical units, making it ideal for both small‑scale prototyping and larger production runs. The device operates from a supply voltage range of 5 V to 15 V, providing flexibility for designs that require different power levels. Its typical propagation delay of 60 ns at a 10 V supply ensures fast switching, while the buffered inputs and outputs guarantee reliable signal integrity even in noisy environments.

Key specifications include a maximum quiescent current of 20 µA at 20 V, a maximum input current of 1 µA at 18 V across the full temperature range, and symmetrical output characteristics that simplify interfacing with other logic families. The part is fully tested for maximum quiescent current, ensuring that each gate meets TI’s stringent quality standards. The package is breadboard‑friendly, allowing engineers and hobbyists to quickly insert the component into standard prototyping boards without the need for additional adapters or sockets.

Usage

This NOR gate is perfectly suited for digital logic circuits, including combinational logic, timing circuits, and simple arithmetic units. Its four‑input configuration enables designers to implement complex logical functions with fewer components, reducing board space and overall cost. Typical applications include microcontroller interfacing, sensor signal conditioning, and educational kits that teach fundamental digital concepts. The device’s low power consumption makes it a good choice for battery‑powered devices, while its robust voltage tolerance supports industrial environments where voltage spikes may occur.

Because the CD4002BE is packaged for easy insertion into a breadboard, it is frequently used in academic labs, maker spaces, and rapid‑development environments where time‑to‑prototype is critical. Engineers can quickly test circuit ideas, iterate designs, and move to production without redesigning the layout. The ten‑unit pack also provides spare parts for future revisions or for building multiple identical circuits in parallel.
