CD4043BM/CD4043BC are quad cross-couple TRI-STATE
CMOS NOR latches, and CD4044BM/CD4044BC are quad
cross-couple TRI-STATE CMOS NAND latches. Each latch
has a separate Q output and individual SET and RESET
inputs. There is a common TRI-STATE ENABLE input for all
four latches. A logic ‘‘1’’ on the ENABLE input connects the
latch states to the Q outputs. A logic ‘‘0’’ on the ENABLE
input disconnects the latch states from the Q outputs resulting
in an open circuit condition on the Q output. The
TRI-STATE feature allows common bussing of the outputs.
