Nexperia | HEF4555BT,652

The HEF4555BT,652 contains two 1-of-4 decoders/demultiplexers. Each 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 V to 15 V referenced to VSS (usually ground). Unused inputs must be connected to VDD, VSS, or another input. It is also suitable for use over the full industrial (-40 °C to +85 °C) temperature range.

Features:

• Fully static operation
• 5 V, 10 V, and 15 V parametric ratings
• Standardized symmetrical output characteristics
• Operates across the full industrial temperature range -40 °C to +85 °C
• Complies with JEDEC standard JESD 13-B

Applications:

• Industrial
• Code conversion
• Address decoding
• Demultiplexing: when using the enable input as data input
