Quiet Series
with 3-STATE Outputs
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
guarantee quiet output switching and improve dynamic
threshold performance. FACT Quiet Series
