EMC CHARACTERISTICS (Cont’d)
13.7.3 Absolute Maximum Ratings (Electrical
Sensitivity)
Based on three different tests (ESD, LU and DLU)
using specific measurement methods, the product
is stressed in order to determine its performance in
terms of electrical sensitivity. For more details, re-
fer to the application note AN1181.
Absolute Maximum Ratings
Notes:
1. Data based on characterization results, not tested in production.
13.7.3.2 Static Latchup
LU: 3 complementary static tests are required on
10 parts to assess the latchup performance. A
supply overvoltage (applied to each power supply
pin) and a current injection (applied to each input,
Electrical Sensitivities
Notes:
1. Class description: A Class is an STMicroelectronics internal specification. All its limits are higher than the JEDEC spec-
ifications, that means when a device belongs to Class A it exceeds the JEDEC standard. B Class strictly covers all the
JEDEC criteria (international standard).

13.7.3.1 Electrostatic Discharge (ESD)
Electrostatic Discharges (a positive then a nega-
tive pulse separated by 1 second) are applied to
the pins of each sample according to each pin
combination. The sample size depends on the
number of supply pins in the device (3 parts*(n+1)
supply pin). The Human Body Model is simulated.
This test conforms to the JESD22-A114A stand-
