74HC139 Dual 2-Line To 4-Line Decoders/Demultiplexers

The SNx4HC139 contains two two-to-four decoders with one active low output strobe G. When the outputs of one channel are gated by the strobe input, they are all forced into the high state. When the outputs are not disabled by the strobe input, only the selected output is low while all others are hi.

74HC139 Features

* Wide operating voltage range of 2 V to 6 V

* Outputs can drive up to 10 LSTTL loads

* Low power consumption, 80-μA max ICC

* Typical tpd = 10 ns

* ±4-mA output drive
