STMicroelectronics HCF4555B Manuals

The HCF4555B is a dual 1 of 4 decoder/demultiplexer integrated circuit with standardized symmetrical output characteristics and multiple packaging options. It has standardized quiescent current and parametric ratings, and meets the requirements of JEDEC JESD13B standard specifications. The product has two select inputs (A and B), an enable input (E), and four mutually exclusive outputs. When the enable input is high, the outputs are low regardless of the state of the select inputs A and B.
