Absolute maximum ratings

Stresses above those listed as ‘absolute maximum ratings’ may cause permanent damage

to the device. This is a stress rating only and functional operation of the device under these

conditions is not implied. Exposure to maximum rating conditions for extended periods may

affect device reliability.

3. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum

cannot be respected, the injection current must be limited externally to the IINJ(PIN) value. A positive

injection is induced by VIN>VDD while a negative injection is induced by VIN<VSS. For true open-drain pads,

there is no positive injection current, and the corresponding VIN maximum must always be respected

4. Negative injection disturbs the analog performance of the device.

5. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the

positive and negative injected currents (instantaneous values). These results are based on characterization

with IINJ(PIN) maximum current injection on four I/O port pins of the device.
