74ACQ240, 74ACTQ240 Quiet Series Octal Buffer/Line Driver with 3-STATE Outputs

March 2007
74ACQ240, 74ACTQ240 tm

Quiet Series Octal Buffer/Line Driver with 3-STATE Outputs
• ICC and IOZ reduced by 50%
• Guaranteed simultaneous switching noise level and
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

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 Series technology to guarantee quiet output switching and improve dynamic threshold performance. FACT Quiet Series features GTO output control and undershoot corrector in addition to a split ground bus for superior performance.

Absolute Maximum Ratings

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
