Description

General part information

SN74AHC238 Series

The SN74AHC238 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 low state. When the outputs are not disabled by the strobe inputs, only the selected output is high while all others are low.
