*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 T_A = -40°C to 85°C and V_CC = 5.0V ± 20%, unless otherwise noted.

1. Under steady state (non-transient) conditions, I_OL must be externally limited as follows:
Maximum I_OL per port pin: 10 mA
Maximum I_OL per 8-bit port:
Port 0: 26 mA
Ports 1, 2, 3: 15 mA
Maximum total I_OL for all output pins: 71 mA
If I_OL exceeds the test condition, V_OL may exceed the related specification. Pins are not guaranteed to sink current greater
than the listed test conditions.
2. Minimum V_CC for Power Down is 2V.
