DESCRIPTION
The HCC40108B (extended temperature range)
and HCF40108B (intermediate temperature range)
are monolithic integrated circuits, available in 24
leaddualinline plasticorceramicpackageand plastic 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 islow, the corresponding output bus
is switched,independently ofthe clock, toahighimpedancestate. The high impedance third stateprovides the outputs with the capability of being
connected to the bus linesin a bus organized system withoutthe needfor interface orpull-up components. When the WRITE ENABLE input is high, all
data input lines arelatchedon thepositive transition
of theCLOCK and thedata is entered intothe word
selected by the write address lines. When WRITE
ENABLE is low, the CLOCK is inhibited and
