Stresses beyond those listed under Absolute Maximum Ratings may 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

Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device

reliability.

6.2 ESD Ratings

VALUE

UNIT

V(ESD)

Electrostatic discharge

Human body model (HBM), per ANSI/ESDA/JEDEC

JS-001, all pins(1)

2500

Charged device model (CDM), per JEDEC

specification JESD22-C101, all pins(2)

1000

(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.
