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.
