ICC and IOZ reduced by 50% Guaranteed simultaneous switching noise level and

General Description
The ACQ/ACTQ573 is a high-speed octal latch with buffered common Latch Enable (LE) and buffered common Output Enable (OE) inputs. The ACQ/ACTQ573 is functionally identical to the ACQ/ACTQ373 but with inputs and outputs on opposite sides of the package. The ACQ/ ACTQ utilizes Fairchild s Quiet SeriesTM technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet SeriesTM features GTOTM output control and undershoot corrector in addition to a split ground bus for superior performance.
