Texas Instruments SN74AC138-Q1 3-to-8 Line Inverting Decoders/Demuxs
Texas Instruments SN74AC138-Q1 3-to-8 Line Inverting Decoders/Demultiplexers contain a three-to-eight decoder with two active low output strobes (G1 and G0) and one standard output strobe (G2). When the Texas Instruments SN74AC138-Q1 outputs are gated by any of the strobe inputs, the inputs are all forced into the high state. The selected output is low, while all others are high when the strobe inputs do not disable the outputs.
