NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification is not implied.
2. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin:
10mA
(NOTE: This is 85
°
C spec.)
Maximum I
OL
per 8-bit port:
26mA
Maximum total I
for all outputs:
67mA
If I
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
3. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.
4. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless otherwise
noted.
5. Power-down I
CC
is measured with all output pins disconnected; port 0 = V

; X2, X1 n.c.; RST = V

.
8. Load capacitance for ports = 80pF.
9. The resistor ladder network is not disconnected in the power down or idle modes. Thus, to conserve power, the user may remove AV
CC
.
10.If the A/D function is not required, or if the A/D function is only needed periodically, AV
CC
may be removed without affecting the operation of
the digital circuitry. Contents of ADCON and ADAT are not guaranteed to be valid. If AV
CC
is removed, the A/D inputs must be lowered to
less than 0.5V. Digital inputs on P1.0–P1.4 will not function normally.
11. These parameters do not apply to P1.0–P1.4 if the A/D function is enabled.
12.The input voltage slew rate should be <10V/ms. The maximum slew rate depends on the clock frequency of the microcontroller. Designers
should use low pass filters before the A/D inputs as a precaution to noise edges causing false readings.
