The ACTQ563 is a high speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The ACTQ563 is functionally identical to the ACTQ573, but with inverted outputs. The ACTQ563 utilizes Fairchild FACT Quiet SeriesTM technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTOTM output control and undershoot corrector in addition to a split ground bus for superior performance.
