Absolute maximum ratings (electrical sensitivity)
Based on two different tests (ESD and LU) using specific measurement methods, the
product is stressed in order to determine its performance in terms of electrical sensitivity.
Electrostatic discharge (ESD)
Electrostatic 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). Two models
can be simulated: Human Body model and Machine model. This test conforms to the
JESD22-A114A/A115A standard. For more details, refer to the application note AN1181.

Static latch-up (LU)
Two complementary static tests are required on six parts to assess the latch-up
performance.
These tests are compliant with the EIA/JESD 78 IC latch-up standard.
