21. Absolute Maximum Ratings*
22. DC Characteristics
The values shown in this table are valid for T
A = -40°C to 85°C and VCC = 2.7V to 6.0V, unless otherwise noted.
Notes:
1. Under steady state (non-transient) conditions, IOL 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, VOL 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 Maxi-
mum Ratings” may cause permanent damage to the
device. This is a stress rating only and functional oper-
ation 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
