CD4043BM CD4043BC Quad TRI-STATE
NOR R S Latches
CD4044BM CD4044BC Quad TRI-STATE
NAND R S Latches
General Description
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 result-
ing in an open circuit condition on the Q output The
TRI-STATE feature allows common bussing of the outputs
Features
Y Wide supply voltage range
3V to 15V
Y Low power
100 nW (typ )
Y High noise immunity
0 45 VDD (typ )
Y Separate SET and RESET inputs for each latch
Y NOR and NAND configuration
Y TRI-STATE output with common output enable
Applications
Y Multiple bus storage
Y Strobed register
Y Four bits of independent storage with output enable
Y General digital logic

AC Parameters are guaranteed by DC correlated testing
Note 1 ‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed they are not meant to imply that the devices
should be operated at these limits The tables of ‘‘Recommended Operating Conditions’’ and ‘‘Electrical Characteristics’’ provide conditions for actual device
operation
Note 2 VSS e 0V unless otherwise specified
Note 3 IOH and IOL are tested one output at a time
