DESCRIPTION
The 74LVC125A 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 1.65 to 3.6 VCC
operations
and
low
power
and
low
noise
applications.
It can be interfaced to 5V signal environment for
inputs in mixed 3.3/5V system.
These devices require the same 3-STATE control
input G to be taken high to make the output go in
to the high impedance state.
It has more 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.
