June 1989
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 specifi cation is not implied. Exposure to absolute maximum rating conditions for external periods may affect device
reliability.
