DESCRIPTION
The 74LVX238 is a low voltage CMOS 3 TO 8
LINE DECODER fabricated with sub-micron
silicon gate and double-layer metal wiring C

MOS
technology. It is ideal for low 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 high.
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 low.
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.
