EMC CHARACTERISTICS (Cont’d)

12.7.3 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. For more details, re-

fer to the application note AN1181.

12.7.3.1 Electro-Static Discharge (ESD)

Electro-Static 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). Two models can be simulated: Human

Body Model and Machine Model. This test con-

forms to the JESD22-A114A/A115A standard.

Absolute Maximum Ratings

Notes:

1. Data based on characterization results, not tested in production.

12.7.3.2 Static Latch-Up

■ LU: 2 complementary static tests are required

on 6 parts to assess the latch-up performance.

A supply overvoltage (applied to each power

supply pin) and 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.
