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.
