IMPROVED LATCH-UP IMMUNITY

TSSOP

Three enable inputs are provided to ease cascade

connection and application of address decoders

for memory systems.

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

DESCRIPTION

The 74ACT138 is an advanced high-speed CMOS

3 TO 8 LINE DECODER (INVERTING) fabricated

with sub-micron silicon gate and double-layer

metal wiring C MOS tecnology.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

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.
