3 Description

The SN74AHC138-Q1 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.
