Description

The SN74AC139-Q1 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 (G = HIGH), they are all forced into the high state. When the outputs are not disabled by the strobe input (G = LOW), only the selected output is low while all others are high.
