DESCRIPTION

The 74VHCT138A is an advanced high-speed

CMOS 3 TO 8 LINE DECODER (INVERTING)

fabricated with sub-micron silicon gate and

double-layer metal wiring C

2MOS 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

G2A or G2B is held high, the decoding function is

inhibited and all the 8 outputs go to high.

Three 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 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.
