CD4043BDR TI CMOS Quad NOR R/S Latch | 16-SOIC | 3V-18V, 5MHz

Product Overview

The CD4043BDR from Texas Instruments is a quad CMOS NOR R/S latch with three-state outputs, designed for general-purpose storage and data retention in digital systems. It operates over a wide supply voltage range of 3V to 18V, making it suitable for battery-powered and industrial applications. The device features four independent latches with set (S) and reset (R) inputs, and each output can be placed in a high-impedance state via a common output enable (OE) input. The CD4043BDR is housed in a 16-pin SOIC package, offering a compact footprint for space-constrained designs.
