4 x 4 MULTIPORT REGISTER

(Plastic Package)
DESCRIPTION
The HCC40108B (extended temperature range)
and HCF40108B (intermediate temperature range)
are monolithic integrated circuits, available in 24
leaddualinline plasticor ceramicpackageand plas-
tic micropackage. The HCC/HCF40108B is a 4 X 4
multiport register containing four 4-bit register, 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,independently ofthe clock,toa highim-
pedancestate. The high impedance third state pro-
vides the outputs with the capability of being
connected to the bus lines in a bus organized sys-
tem withoutthe need for interface orpull-up compo-
nents. When the WRITE ENABLE input is high, all
data input linesare latched on thepositivetransition
of theCLOCK and thedata is entered into theword
selected by the write address lines. When WRITE
ENABLE is low, the CLOCKis inhibited and
