CD4044BDR TI Quad NOR R/S Latch | 16-SOIC | 3V-18V, 5MHz

Product Overview

The CD4044BDR from Texas Instruments is a quad NOR R/S latch with 3-state outputs, designed for general-purpose storage and data retention in digital systems. Fabricated with CMOS technology, it offers low power consumption and high noise immunity. The device operates over a wide supply voltage range of 3V to 18V, making it suitable for battery-powered and industrial applications. Each latch has independent set (S) and reset (R) inputs, and the outputs can be disabled via a common output enable (OE) input. The CD4044BDR is housed in a 16-pin SOIC package, ideal for space-constrained designs.
