DESCRIPTION
The
HCC4555B, HCC4556B
(extended tempera-
ture range) and the
HCF4555B, HCF4556B
(inter-
mediate temperature range) are monolithic
integrated circuits available in 16-lead dual in-line
plastic or ceramic package and plastic micropack-
age.
The
HCC/HCF4555B
and
HCC/HCF4556B
are
dual one-of-four decoders/demultiplexers. Each
decoder has two select inputs (A and B), an Enable
input (E), and four mutually exclusive outputs. On
the
HCC/HCF4555B
the outputs are high on select ;
on the
HCC/HCF4556B
the outputs are low on se-
lect. When the Enable input is high, the outputs of
the
HCC/HCF4555B
remain low and the outputs of
the
HCC/HCF4556B
remain high regardless of the
state of the select inputs A and B.

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 sec-
tions of this specification is not implied. Exposure to absolute maximum rating conditions for external periods may affect device
reliability.
