CD4044BC Datasheet Quad 3-state Nand R/s Latches

Manufacturer: Fairchild (now onsemi)

Overview: CD4043BC • CD4044BC Quad 3-STATE NOR R/S Latches • Quad 3-STATE NAND R/S Latches October 1987 Revised January 1999 CD4043BC • CD4044BC Quad 3-STATE NOR R/S Latches • Quad 3-STATE NAND R/S Latches.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The CD4043BC are quad cross-couple 3-STATE CMOS NOR latches, and the CD4044BC are quad cross-couple 3STATE CMOS NAND latches.

Each latch has a separate Q output and individual SET and RESET inputs.

There is a common 3-STATE ENABLE input for all four latches.
