Automotive 3-Line to 8-Line inverting Decoders/Demultiplexers

The SN74ACT138-Q1 contains 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. TTL-compatible CMOS inputs provide the capability to up-translate input signals from as low as 2V up to 5V outputs.
