DESCRIPTION
The M74HCT138 is an high speed CMOS 3 TO 8
LINE DECODER fabricated with silicon gate
C
If the device is enabled, 3 binary select inputs (A,
B, and C) determine which one of the outputs will
go low. If enable input G1 is held low or either G2A
or G2B is held high, the decoding function is
inhibited and all the 8 outputs go high. Three
