Quiet Series錚?Octal Buffer/Line Driver
with 3-STATE Outputs
General Description
The ACQ/ACTQ244 is an octal buffer and line driver
designed to be employed as a memory address driver,
clock driver and bus oriented transmitter or receiver which
provides improved PC board density. The ACQ/ACTQ uti-
lizes Fairchild Quiet Series錚?technology to guarantee quiet
output switching and improved dynamic threshold perfor-
mance. FACT Quiet Series錚?features GTO錚?output control
and undershoot corrector in addition to a split ground bus
for superior performance.
