DESCRIPTION
The 74LVX138 is a low voltage CMOS 3 TO 8
LINE DECODER (INVERTING) fabricated with
sub-micron silicon gate and double-layer metal
wiring C
power, battery operated and low noise 3.3V
applications.
If the device is enabled, 3 binary select (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 to high.
Tree enable inputs are provided to ease cascade
connection and application of address decoders
for memory systems.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage.
This device can be used to interface 5V to 3V
system. It combines high speed performance with
the true CMOS low power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
