74ACTQ563 Quiet Series Octal Latch with 3-STATE Outputs
General Description
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 Series technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
Features
s ICC and IOZ reduced by 50% s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed pin-to-pin skew AC performance s Improved latch-up immunity s Inputs and outputs on opposite sides of package allow easy interface with microprocessors s Outputs source/sink 24 mA s Faster prop delays than standard ACT563 s Functionally identical to the ACTQ573 but with inverted outputs
