NOTES FOR DC ELECTRICAL CHARACTERISTICS

CC

DD

4.
Port 1, 2, 3, and 4 sources a transition current when they are being externally driven from HIGH to LOW. The transition current reaches its
maximum value when V
IN
is approximately 2V.
5.
Capacities loading on port 0 and 2 may cause spurious noise to be superimposed on V
OL
of ALE and port 1, 3, and 4. The noise is due to external
bus capacitance discharging into port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations. In the worst cases
(capacities loading > 100pF), the noise pulse on the ALE pin may exceed 0.8V. In such cases, it may be desirable to qualify ALE with a Schmitt
Trigger, or use an address latch with a Schmitt trigger STROBE input.
6.
Under steady state (non-transient) conditions, IOL must be externally
Limited as follows:
Maximum IOL per pin (use sign pin only) : 10mA
Maximum IOL per 8-bit port :
port 0 : 26mA
port 1,2,3 : 15mA
Maximum total IOL for all output pins : 71mA
If IOL exceeds the condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions.
