NOTES TO DC ELECTRICAL CHARACTERISTICS:
1. Parameters are valid over operating temperature range unless otherwise specified. All voltages are with respect to V
SS
unless otherwise
noted.
2. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin:
10mA
Maximum I
per 8-bit port:
26mA
Maximum total I
OL
for all outputs:
67mA
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.
3. Pins of ports 1 and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its
maximum value when V
IN
is approximately 2V.
4. Power-down I
CC
is measured with all output pins disconnected; port 0 = V
CC
; X2, X1 n.c.; RST = V

.
5. Active I
CC
is measured with all output pins disconnected; X1 driven with t
CLCH

– 0.5V; X2 n.c.;
RST = port 0 = V
CC
. I
CC
will be slightly higher if a crystal oscillator is used.
6. Idle I
CC
is measured with all output pins disconnected; X1 driven with t
CLCH
, t
