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
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 the clock 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 bythewrite address 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.

Stresses above those listed under ”Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device reliability.
* All voltages are with respect to VSS (GND).
