must be externally limited as follows:

Maximum I

Port 0: 26 mA

Ports 1, 2, 3: 15 mA

Maximum total IOL for all output pins: 71mA

related specification. Pins are not guaranteed to sink

current greater than the listed test conditions.

2. Minimum V

Operating Temperature.................................. -55°C to +125°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 .....................................-1.0V to +7.0V

Maximum Operating Voltage ............................................ 6.0V

DC Output Current...................................................... 15.0 mA
