General Description
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 Series™ technology to
guarantee quiet output switching and improved dynamic
threshold performance. FACT Quiet Series™ features
GTO™ output control and undershoot corrector in addi-
tion to a split ground bus for superior performance.
dynamic threshold performance
Guaranteed pin-to-pin skew AC performance
Improved latch-up immunity
3-STATE outputs drive bus lines or buffer memory
address registers
Outputs source/sink 24mA
Faster prop delays than the standard AC/ACT244
