DESCRIPTION
The 74ACT125 is an advanced high-speed CMOS
QUAD BUS BUFFER fabricated with sub-micron
silicon gate and double-layer metal wiring C2MOS
technology.
This device require the 3-STATE control input G to
be set high to place the output in high impedance
state.
The device is designed to interface directly High
Speed CMOS systems with TTL, NMOS and
CMOS output voltage levels.
All
inputs
and
outputs
are
equipped
with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
