Automotive 2V-to-5.5V 3-line to 8-line decoder and demultiplexer

The SN74AHC138-Q1 is a three to eight decoder with one standard output strobe (G2) and two active low output strobes (G1 and G0). 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.
