*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.

DC Characteristics

The values shown in this table are valid for TA = -40°C to 85°C and VCC = 2.7V to 6.0V, unless otherwise noted.

1. Under steady state (non-transient) condition, IOL

must be externally limited as follows:

Maximum IOL per port pin: 10 mA

Maximum IOL per 8-bit port: Port 0: 26 mA

Ports 1, 2, 3: 15 mA

Maximum total IOL or all output pins: 71 mA

If IOL exceeds the test condition, VOL may exceed the

related specification. Pins are not guaranteed to sink

current greater than the listed test conditions.

2. Minimum VCC for Power Down is 2V.
