4 x 4 MULTIPORT REGISTER
DESCRIPTION
The
HCC40208B
(extended temperature range) and
HCF40208B
(intermediate temperature range) are
monolithic integrated circuits,available in24-lead dual
in-line plastic or ceramic package and plastic micro
package. The
HCC/HCF40208B
is a 4 x 4 multiport
register containing four 4-bit registers, write address
decoder, two separate read address decoders, and
two 3-state output buses. When the ENABLE input is
low, the corresponding output bus is switched, inde-
pendently of theclock to a high-impedance state. The
high-impedance third state provides the outputs with
thecapability of being connected to the bus lines in a
bus-organized systemwithouttheneed forinterface or
pull-up components. When the WRITEENABLE input
is high, all data input lines are latched on the positive
transitionoftheCLOCKandthedataisenteredintothe
wordselectedbythewriteaddresslines.WhenWRITE
ENABLE is low, the CLOCK is inhibited and no new
dataisentered. Ineithercase,thecontentsofanyword
may be accessed via the read address lines inde-
pendent ofthe state of the CLOCKinput.
