Product Summary
The CD74HC139M96 is a High-Speed CMOS Logic Dual 2- to 4-Line Decoder/Demultiplexer. It contains two independent binary to one of four decoders each with a single active lowenable input (1E or 2E). Data on the select inputs (1A0 and 1A1 or 2A0 and 2A1) cause one of the four normally high outputs to go low. If the enable input is high all four outputs remain high. For demultiplexer operation the enable input is the data input. The enable input also functions as a chip select when the CD74HC139M96 is cascaded. The CD74HC139M96 is functionally the same as the CD4556B and is pin compatible with it.
