CD4508BM TI CMOS Dual 4-Bit Latch | 24-SOIC | 3V-18V, 100ns

Product Overview

The CD4508BM is a CMOS dual 4-bit latch from Texas Instruments, designed for general-purpose storage and data retention in digital systems. It features two independent 4-bit latches with common enable and reset controls, making it ideal for temporary data storage, address latching, and control signal buffering. The device operates over a wide supply voltage range of 3V to 18V, offering high noise immunity and low power consumption typical of CMOS technology. Housed in a compact 24-SOIC package, the CD4508BM is suitable for space-constrained applications requiring reliable logic-level latching.
