Description for the SN74ACT139
The SN74ACT139 contains two two-to-four decoders with one active low output strobe (G). When the strobe input is inactive (G = HIGH), the outputs for that channel are all forced into the high state. When strobe input is active (G = LOW), only the selected output is low while all others are high.
