74ACQ241 Octal Buffer/Line Driver with 3-STATE Outputs
January 1990
Revised September 1998
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鈩?technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Series features GTO鈩?output control and
undershoot corrector in addition to a split ground bus for
superior performance.
