Description
The 74LCX125 device is a low-voltage CMOS
quad bus buffer manufactured with sub-micron
silicon gate and double-layer metal wiring C
2
MOS
technology. It is ideal for low-power and high-
speed 3.3 V applications and can be interfaced to
a 5 V 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 the high
impedance state.
It has the same speed performance at 3.3 V as
the 5 V AC/ACT family, combined with lower
power consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2 kV ESD immunity and transient excess
voltage.
