Static latch-up10.3.11.6
Two complementary static tests are required on 10 parts to assess the latch-up performance:
•
A supply overvoltage (applied to each power supply pin)
•
A current injection (applied to each input, output and configurable I/O pin) are performed
on each sample.
This test conforms to the EIA/JESD 78 IC latch-up standard. For more details, refer to the
application note AN1181.

Class description: A Class is an STMicroelectronics internal specification. All its limits
are higher than the JEDEC specifications, that means when a device belongs to class A it
exceeds the JEDEC standard. B class strictly covers all the JEDEC criteria (international
standard).
