74ACQ244 • 74ACTQ244
Quiet Series
 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
 technology to guarantee quiet
output switching and improved dynamic threshold perfor-
mance. FACT Quiet Series
 features GTO output control
and undershoot corrector in addition to a split ground bus
for superior performance.
Features
s ICC and IOZ reduced by 50%
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Improved latch-up immunity
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs source/sink 24 mA
s Faster prop delays than the standard AC/ACT244
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
