18. Electrical Characteristics
Notes:
1. Under steady state (non-transient) conditions, I
OL must be externally limited as follows:
Maximum IOL per port pin: 10 mA
Maximum total IOL for all output pins: 100 mA
If I
OL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test conditions.
18.1
Absolute Maximum Ratings*
Operating Temperature ................................... -40°C to +85°C
*NOTICE:
Stresses beyond those listed under “Absolute
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect
device reliability.
Storage Temperature ..................................... -65°C to +150°C
Voltage on Any Pin with Respect to Ground ......-0.7V to +5.5V
Maximum Operating Voltage ............................................ 5.5V
Total DC Output Current ........................................... 150.0 mA
