CD4071BM

CD4071BM Description

The CD4071BM from Texas Instruments is a quad 2-input OR gate integrated circuit (IC) belonging to the 4000B series, designed for high-performance logic operations. Housed in a 14-pin SOIC package, this surface-mount device operates over a wide voltage range (3V to 18V), making it versatile for both low-power and industrial applications. With a maximum propagation delay of 90ns at 15V and 50pF load, it ensures reliable signal processing in digital systems. The IC features low quiescent current (1 µA max), enhancing energy efficiency, and supports balanced output drive (3.4mA sink/source current) for robust signal integrity.
