74ACQ241
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
switching and improved dynamic threshold performance.
FACT Quiet Series features GTO
undershoot corrector in addition to a split ground bus for
superior performance.
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
