OPERATING VOLTAGERANGE:

G2A or G2B is held high, the decoding function is

inhibited and all the 8 outputsgo to high.

Three enable inputs are provided to ease

cascade connection and application of address

decodersfor memory systems.

V_CC(OPR)= 2V to 5.5V

PIN AND FUNCTION COMPATIBLEWITH

74 SERIES138

IMPROVED LATCH-UP IMMUNITY

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 interface5V 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-layermetal wiring C²MOS 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
