NSC DM54132 Dm54132/dm74132 quad 2-input nand gates with schmitt trigger input Datasheet

DM54132/DM74132 Quad 2-Input NAND Gates with
Schmitt Trigger Inputs
General Description
This device contains four independent gates each of which
performs the logic NAND function. Each input has hysteresis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter-free
output.

Absolute Maximum Ratings (Note)
If Military/Aerospace specified devices are required,
please contact the National Semiconductor Sales
Office/Distributors for availability and specifications.
Note: 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’’
table are not guaranteed at the absolute maximum ratings.
The ‘‘Recommended Operating Conditions’’ table will define
the conditions for actual device operation.
