74ACQ240, 74ACTQ240 Rev. 1.6
74ACQ240, 74ACTQ240
Quiet Series™ Octal Buffer/Line Driver with 3-STATE
Outputs
Features
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
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 Series™ technol-
ogy 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 perfor-
mance.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
