DM74LS132
Quad 2-Input NAND Gate with Schmitt Trigger Input
General Description
This device contains four independent gates each of which
performs the logic NAND function. Each input has hystere-
sis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter free
output.
Ordering Code:
Devices also available in Tape and Reel. Specify by appending the suffix letter "X" to the ordering code.

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" table are not guaranteed at the absolute maximum ratings.
The "Recommended Operating Conditions" table will define the conditions
for actual device operation.
