DESCRIPTION
The 74VHCT238A is an advanced high-speed
CMOS 3 TO 8 LINE DECODER fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology.
If the device is enabled, 3 binary select inputs (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, decoding function is
inhibited and all the 8 outputs go to low.
Three enable inputs are provided to ease
cascade connection and application of this
address decoders for memory systems.
Power down protection is provided on all inputs
and outputs 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.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
