MC74HC139A Dual 1-of-4 Decoder/ Demultiplexer
MC74HC139A identical pinout LS139. device inputs compatible with standard CMOS outputs; with pullup resistors, they compatible with LSTTL outputs. This device consists independent 1-of-4 decoders, each which decodes two-bit Address one-of-four active-low outputs. Active-low Selects provided facilitate demultiplexing cascading functions. demultiplexing function accomplished using Address inputs select desired device output, utilizing Select data input.
