54ACQ244 • 54ACTQ244
Quiet Series Octal Buffer/Line Driver with TRI-STATE®
Outputs
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
General Description
The ’ACQ/’ACTQ244 is an octal buffer and line driver de-
n Improved latch-up immunity
signed to be employed as a memory address driver, clock
n TRI-STATE outputs drive bus lines or buffer memory
driver and bus oriented transmitter or receiver which pro-
address registers
vides improved PC board density. The ACQ/ACTQ utilizes
NSC Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.
n Outputs source/sink 24 mA
n Faster prop delays than the standard ’AC/’ACT244
n 4 kV minimum ESD immunity
n Standard Microcircuit Drawing (SMD)
— ’ACTQ244: 5962-92186
™
™
FACT Quiet Series features GTO output control and un-
dershoot corrector in addition to a split ground bus for supe-
rior performance.

Note 1: Absolute maximum ratings are those values beyond which damage
to the device may occur. The databook specifications should be met, without
exception, to ensure that the system design is reliable over its power supply,
temperature, and output/input loading variables. National does not recom-
mend operation of FACT® circuits outside databook specifications.
