23 Electrical Characteristics
23.1 Maximum Ratings
The maximum ratings are the limits to which the device can be subjected without permanently
damaging the device. Device reliability may be adversely affected by exposure to absolute-maximum
ratings for extended periods.
Note: The device is not guaranteed to operate properly at the maximum ratings.

a. Voltages are measured with respect to GND.
b. Applies to static and dynamic signals including overshoot.
Important: This device contains circuitry to protect the inputs against damage due to high-static
voltages or electric fields; however, it is advised that normal precautions be taken to
avoid application of any voltage higher than maximum-rated voltages to this
high-impedance circuit. Reliability of operation is enhanced if unused inputs are
connected to an appropriate logic voltage level (see “Connections for Unused
Signals” on page 977).
23.2 Recommended Operating Conditions
For special high-current applications, the GPIO output buffers may be used with the following
restrictions. With the GPIO pins configured as 8-mA output drivers, a total of four GPIO outputs may
be used to sink current loads up to 18 mA each. At 18-mA sink current loading, the V
OL
value is
specified as 1.2 V. The high-current GPIO package pins must be selected such that there are only
a maximum of two per side of the physical package or BGA pin group with the total number of
high-current GPIO outputs not exceeding four for the entire package.
