DESCRIPTION

The M74HC138 is an high speed CMOS 3 TO 8

LINE DECODER fabricated with silicon gate

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
