DESCRIPTION
The 74VHCT138A is an advanced high-speed
CMOS 3 TO 8 LINE DECODER (INVERTING)
fabricated with sub-micron silicon gate
double-layermetal wiring C
2
MOS technology.
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
and
G2A or G2B is held high, the decoding functionis
inhibited and all the 8 outputsgo to high.
Three enable inputs are provided to ease
cascade connection and application of address
decodersfor 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 interface5V to 3V.
All
inputs
and
outputs are
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
