DESCRIPTION
The AC125 is an high-speed CMOS QUAD BUS
BUFFERS fabricated with sub-micron silicon gate
and
double-layer
metal
technology. It is ideal for low power applications
maintaining high speed operation similar to
wiring
C

MOS
equivalentBipolar Schottky TTL.
These devices require the same 3-STATE control
input G to be taken high to make the output go in
to the high impedancestate.
All
inputs and
outputs
protectioncircuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
