Description

CD4043BMS types are quad cross-coupled 3-state CMOS NOR

latches and the CD4044BMS types are quad cross-coupled 3-

state CMOS NAND latches. Each latch has a separate Q output

and individual SET and RESET inputs. The Q outputs are controlled by a common ENABLE input. A logic “1” or high on the

ENABLE input connects the latch states to the Q outputs. A logic

“0” or low on the ENABLE input disconnects the latch states from

the Q outputs, results in an open circuit feature allows common

busing of the outputs.

The CD4043BMS and CD4044BMS are supplied in these 16-

lead outline packages:
