74ACQ241
Octal Buffer/Line Driver with 3-STATE Outputs
General Description
The ACQ241 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 utilizes Fairchild
FACT Quiet Seriestechnology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Series features GTOoutput 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
