Absolute maximum ratings (electrical sensitivity)

Based on three different tests (ESD, LU) using specific measurement methods, the device is

stressed in order to determine its performance in terms of electrical sensitivity.

Electrostatic discharge (ESD)

Electrostatic discharges (a positive then a negative pulse) are applied to the pins of each

sample according to each pin combination. This test conforms to the ANSI/ESDA/JEDEC

JS-001 and ANSI/ESDA/JEDEC JS-002 standards.

Static latchup

Two complementary static tests are required on six parts to assess the latchup

performance:

•

A supply overvoltage is applied to each power supply pin

•

A current injection is applied to each input, output and configurable I/O pin

These tests are compliant with JESD78 IC latchup standard.
