74ACQ241 Octal Buffer/Line Driver with 3-STATE Outputs

The ACQ241 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 utilizes Fairchild FACT Quiet technology to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series 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

Note 1 Absolute maximum ratings are those values beyond which damage to the device may occur. The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. Fairchild does not recommend operation of circuits outside databook specifications.
