IO0

I/O

General-purpose digital IO. If unused, TI recommends to connect pin to ground

IO1

I/O

General-purpose digital IO. If unused, TI recommends to connect pin to ground

IO2/ALERT

I/O

General-purpose digital IO or configurable as temperature alert. If unused, TI recommends to

connect pin to ground

IO3

I/O

General-purpose digital IO. If unused, TI recommends to connect pin to ground

SDQ

I/O

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.

7.2 ESD Ratings

VALUE

(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.
