The SN74HCS138 is a three to eight decoder with one standard output strobe (G2) and two active low output strobes (G 1 and G 0). When the outputs are gated by any of the strobe inputs, they are all forced into the high state. When the outputs are not disabled by the strobe inputs, only the selected output is low while all others are high.
