1-of-8 Decoder/Demultiplexer
High-Speed Silicon-Gate CMOS
The KK74AC138 is identical in pinout to the LS/ALS138, HC/HCT138. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible with LS/ALS outputs. The KK74AC138 decodes a three-bit Address to one-of-eight activelow outputs. This device Features three Chip Select inputs, two active-low and one active-high to facilitate the demultiplexing, cascading, and chipselecting functions. The demultiplexing function is acplished by using the Address inputs to select the desired device output; one of the Chip Selects is used as a data input while the...
