PIN AND FUNCTION COMPATIBLE WITH

74 SERIES 138

IMPROVED LATCH-UP IMMUNITY

TSSOP

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.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.

DESCRIPTION

The 74VHC138 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 technology.

If the device is enabled, 3 binary select (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.
