DESCRIPTION
The 74AC244 is an advanced high-speed CMOS
OCTAL BUS BUFFER (3-STATE) fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS tecnology.
The G input controls four BUS BUFFERs.
This device is designed to be used with 3 state
memory address drivers, etc.
All
inputs
and
outputs
are
equipped
with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
