Dual 1-of-4 Decoder/Demultiplexer
High-Speed Silicon-Gate CMOS
The KK74AC139 is identical in pinout to the LS/ALS139, HC/HCT139. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALS outputs. This device consists of two independent 1-of-4 decoders, each of which decodes a two-bit Address to one-of-four active-low outputs. Active-low Selects are provided to facilitate the demultiplexing and cascading functions. The demultiplexing function is acplished by using the Address inputs to select the desired device output, and utilizing the Select as a data input.
