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 con-
trolled by a common ENABLE input. A logic â1â or high on the
ENABLE input connects the latch states to the Q outputs. A logic
â0â 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:
