Quiet Series Octal Buffer/Line Driver with TRI-STATE
Outputs
General Description
The ’ACQ/’ACTQ244 is an octal buffer and line driver de-
signed to be employed as a memory address driver, clock
driver and bus oriented transmitter or receiver which pro-
vides improved PC board density. The ACQ/ACTQ utilizes
NSC Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Series
features GTO
output control and un-
dershoot corrector in addition to a split ground bus for supe-
rior performance.
