74LCX138

Low voltage CMOS 3 to 8 line decoder (Inverter)

with 5V tolerant inputs

Features

■ 5V tolerant inputs

■ High speed:

– t = 6.7ns (Max) at V = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

SO-16

TSSOP16

– |I | = I = 24mA (Min) at V = 3V

■ PCI bus levels guaranteed at 24mA

■ Balanced propagation delays:

Description

– t

≅ t

The 74LCX138 is a low voltage CMOS 3 to 8 line

decoder (inverting) fabricated with sub-micron

silicon gate and double-layer metal wiring C MOS

technology. It is ideal for low power and high

speed 3.3V applications; it can be interfaced to

5V signal environment for inputs.

PLH

PHL

■ Operating voltage range:

– V (Opr) = 2.0V to 3.6V

■ Pin and function compatible with

74 series 138

■ Latch-up performance exceeds

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.

500mA (JESD 17)

■ ESD performance:

– HBM > 2000V

(MIL STD 883 method 3015); MM > 200V

Three enable inputs are provided to ease

cascade connection and application of address

decoders for memory systems.

It has same speed performance at 3.3V than 5V

AC/ACT family, combined with a lower power

consumption.

All inputs and outputs are equipped with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
