DESCRIPTION

The HCF4555B is a monolithic integrated circuit

fabricated

in

Metal

Oxide

Semiconductor

technology available in DIP and SOP packages.

The HCF4555B is a dual 1 of 4 decoder/

demultiplexer. Each decoder has two select inputs

(A and B), an Enable input (E), and four mutually

exclusive outputs. On the HCF4555B the outputs

are high on select. When the Enable input is high,

the outputs is low regardless of the state of the

select inputs A and B.
