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

General Description
The ACQ/ACTQ374 is a high-speed, low-power octal D-type flip-flop featuring separate D-type inputs for each flip-flop and 3-STATE outputs for bus-oriented applications. A buffered Clock (CP) and Output Enable (OE) are common to all flip-flops. The ACQ/ACTQ374 utilizes FACT Quiet SeriesTM technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series features GTOTM output control and undershoot corrector in addition to a split ground bus for superior performance.

dynamic threshold performance
Guaranteed pin-to-pin skew AC performance Improved latch-up immunity Buffered positive edge-triggered clock 3-STATE outputs drive bus lines or buffer memory

address registers
Outputs source/sink 24mA Faster prop delays than the standard AC/ACT374
