AUTOMOTIVE 80C31BH/80C51BH/87C51
NOTES:
(Continued)
4. Pins of Ports 1, 2 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.
5. ICCMAX at other frequencies is given by:

test conditions. Minimum V
CC
for Power Down is 2.0V.
7. Under steady state (non-transient) conditions, 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, and 3:
15 mA
Maximum total I
OL
for 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.
