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.
