Absolute maximum ratings (electrical sensitivity)
Based on two different tests (ESD and LU) using specific measurement methods, the device
is stressed in order to determine its performance in terms of electrical sensitivity.
Electro-static discharge (ESD)
Electro-static discharges (a positive then a negative 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). This test
conforms to the AEC-Q100-002/003/011 standard. For more details, refer to the application
note AN1181.

Static latch-up
Two complementary static tests are required on six parts to assess the latch-up
performance:
●
●
These tests are compliant with EIA/JESD 78A and AEC-Q100/004 IC latch-up standards.
