74LCX125

Low voltage CMOS quad bus buffer (3-State)

with 5V tolerant inputs and outputs

Features

■ 5V tolerant inputs and outputs

■ High speed:

–tPD = 5.2ns (Max) at VCC = 3V

■ Power down protection on inputs and outputs

■ Symmetrical output impedance:

–|IOH| = IOL = 24mA (Min) at VCC = 3V

■ PCI bus levels guaranteed at 24mA

■ Balanced propagation delays:

–tPLH ≅ tPHL

■ Operating voltage range:

–VCC (Opr) = 2.0V to 3.6V

■ Pin and function compatible with

74 series 125

■ Latch-up performance exceeds

500mA (JESD 17)

■ ESD performance:

– HBM > 2000V

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

Description

The 74LCX125 is a low voltage CMOS quad bus

buffer fabricated with sub-micron silicon gate and

double-layer metal wiring C2MOS technology. It is

ideal for low power and high speed 3.3V

applications; it can be interfaced to 5V signal

environment for both inputs and outputs.

The device requires the 3-STATE control input G

to be set high to place the output in to the high

impedance state.

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.
