DM7414
Hex Inverter with Schmitt Trigger Input
General Description
This device contains six independent gates each of which
performs the logic INVERT function. Each input has hyster-
esis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter free
output.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratings” are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum ratings.
The “Recommended Operating Conditions” table will define the conditions
for actual device operation.
