(1)

Stresses beyond those listed under Section 6.1 can cause permanent damage to the device. These are stress ratings only, which do

not imply functional operation of the device at these or any other conditions beyond those indicated under Section 6.3 . Exposure to

absolute maximum rated conditions for extended periods can affect device reliability.

(2)

All digital inputs and IOs are failsafe.

6.2 ESD Ratings

VALUE

UNIT

V(ESD)

Electrostatic discharge

Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1)

±2000

Charged-device model (CDM), per ANSI/ESDA/JEDEC JS-002(2)

±500

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
