Quiet Series⢠Octal Buffer/Line Driver with 3-STATE
Outputs
Features
â ICC and IOZ reduced by 50%
â Guaranteed simultaneous switching noise level and
dynamic threshold performance
â Guaranteed pin-to-pin skew AC performance
â Improved latch-up immunity
â Inverting 3-STATE outputs drive bus lines or buffer
memory address registers
â Outputs source/sink 24mA
â 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 Seriesâ¢
features GTO⢠output control and undershoot corrector
in addition to a split ground bus for superior perfor-
mance.
