CD4044BD

CD4044BD Description

The CD4044BD from Texas Instruments is a quad NAND R/S latch integrated circuit (IC) belonging to the 4000B series, designed for reliable digital logic applications. Packaged in a 16-SOIC tube, this surface-mount IC operates across a wide voltage range (3V to 18V), making it versatile for various power supply conditions. With four independent 1:1 circuits, it provides robust latching functionality, ensuring stable signal retention in digital systems. The device boasts a propagation delay of 50ns and symmetrical output current (6.8mA sink/source), enabling efficient interfacing with other logic families. Its ROHS3 compliance and REACH-unaffected status ensure environmental and regulatory adherence.
