Absolute Maximum Ratings*
Operating Temperature................... -55°C to +125°C
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
*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 operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
DC Output Current ....................................... 15.0 mA
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.

Notes: 1. Under steady state (non-transient) conditions,
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 for 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.
