Overview
The CD4044BDT is a quad cross-coupled 3-state CMOS NAND latch produced by Texas Instruments. This component is part of the CD4044B series, which is designed for use in digital logic circuits. Each latch in the CD4044BDT has a separate Q output and individual SET and RESET inputs, allowing for independent control of each latch. The Q outputs are controlled by a common ENABLE input, which can connect or disconnect the latch states from the Q outputs, facilitating common busing of the outputs.
