(1) 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.

(2) Input pins are diode-clamped to the power-supply rails. Input signals that can swing beyond the supply rails must be current limited to 10

mA or less.

7.2 ESD Ratings

VALUE

UNIT

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

V_(ESD)

Electrostatic discharge

Charged-device model (CDM), per JEDEC specification JESD22-C101 or

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.
