Quiet Octal Buffer/Line Driver with 3-STATE Outputs

The ACQ/ACTQ244 is an 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 Quiet technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet features output control and undershoot corrector in addition to a split ground bus for superior performance.
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 3-STATE outputs drive bus lines or buffer memory
address registers s Outputs source/sink 24 mA s Faster prop delays than the standard AC/ACT244
