DM74LS132 Quad 2-Input NAND Gate with Schmitt Trigger Input
DM74LS132
Quad 2-Input NAND Gate with Schmitt Trigger Input
General Description
This device contains four independent gates each of which
performs the logic NA ND fu nctio n. Each input has hyster esis which increases the noise immunity and transforms a
slowly changing input signal to a fast changing, jitter free
output.
Ordering Code:
Devices also availab le in Tape and Reel. Specify by appending th e s uffix let t er “X” to the ordering code.

Absolute Maximum Ratings(Note 1)
Note 1: The “Absolute Maximum Ratin gs” are those v alues beyon d which
the safety of the dev ice cannot be guaranteed. T he device sh ould not be
operated at these limits. The paramet ric values defined in the “Electrical
Characteristics” ta ble are not guaranteed at the absolute maximum ratings.
The “Recommend ed O peratin g Cond itions” t able w ill defin e the co ndition s
for actual device operation.
