Product Summary

The MC74HC139AN is identical in pinout to the LS139. The device inputs are compatible with standard CMOS outputs; with pull-up resistors, they are compatible with LSTTL outputs. The MC74HC139AN 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 of the MC74HC139AN is accomplished by using the address inputs to select the desired device output and utilizing the select as a data input.
