The ACQ/ACTQ utilizes Fairchild's Quiet Series™ technol- ogy to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series™ features GTO™ output control and undershoot corrector in addition to a split ground bus for superior perfor- mance. Ordering Information Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
