54ACTQ32
Quiet Series Quad 2-Input OR Gate
General Description
The 'ACTQ32 contains four, 2-input OR gates and utilizes
NSC Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Series
TM
features GTO

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
