Absolute Maximum Ratings*
DC Characteristics
The values shown in this table are valid for T
A
= -40°C to 85°C and V
CC
= 2.7V to 6.0V, unless otherwise noted.
Notes:
1. Under steady state (non-transient) condition, 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
or 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.
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............................................. 6.6V
DC Output Current...................................................... 15.0 mA
