HEF4555BP

The HEF4555BP is an 1-of-4 Decoder/Demultiplexer has two address inputs (nA0 and nA1, an active low enable input (nE\) and four mutually exclusive outputs which are active high (nY0 to nY3). When used as a decoder, nE\ when high, forces nY0 to nY3 low. When used as a demultiplexer, the appropriate output is selected by the information on nA0 and nA1 with nE\ as data input. All unselected outputs are low. It operates over a recommended VDD power supply range of 3 to 15V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS or another input.

• Fully static operation
• Standardized symmetrical output characteristics
• Complies with JEDEC standard JESD 13-B
