DESCRIPTION

The HCC40208B (extended temperature range) and

HCF40208B (intermediate temperature range) are

monolithic integrated circuits, available in 24-lead dual

in-line plastic or ceramic package and plastic micro

package. The HCC/HCF40208B is a 4 x 4 multiport

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

the capability of being connected to the bus lines in a

bus-organized system without the need for interface or

pull-up components. When the WRITE ENABLE input

is high, all data input lines are latched on the positive

transition of the CLOCKand the data is entered into the

wordselected bythewriteaddress lines. When WRITE

ENABLE is low, the CLOCK is inhibited and no new

data is entered. In either case, the contents of any word

may be accessed via the read address lines inde-

pendent of the state of the CLOCK input.
