DESCRIPTION
The 74LVX125 is a low voltage CMOS QUAD
BUS BUFFERs fabricated with sub-micron silicon
gate and double-layer metal wiring C2MOS
technology. It is ideal for low power, battery
operated and low noise 3.3V applications.

This device requires the 3-STATE control input G
to be set high to place the output into the high
impedance state.
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. It combines high speed
performance with the true CMOS low power
consumption.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
