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

General Description
The ACQ/ACTQ240 is an inverting octal buffer and line driver designed to be employed as a memory address driver, clock driver and bus oriented transmitter or receiver which provides improved PC board density. The ACQ/ACTQ utilizes Fairchild s Quiet SeriesTM technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet SeriesTM 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 Inverting 3-STATE outputs drive bus lines or buffer

memory address registers Outputs source/sink 24mA Faster prop delays than the standard ACT240
