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 Series™ technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Series features GTO™ output control and
undershoot corrector in addition to a split ground bus for
superior performance.
Features
s I_CC and I_OZ 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
