DESCRIPTION

The M54/74HC138 is a high speed CMOS 3 TO 8

LINE DECODER fabricated in silicon gate C²MOS

technology.

PIN CONNECTIONS (top view)

It has the same high speed performance of LSTTL

combined with true CMOS low power consumption.

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 enable inputs are provided to ease cascade

connection and application of address decoders for

memory systems. All inputs are equipped with pro-

tection circuits against static discharge and tran-

sient excess voltage.
