1. Under steady state (non-transient) conditions, IOL must be externally limited as follows:
Maximum IOL per port pin:
15mA
Maximum IOL per 8-bit port:
26mA
Maximum IOL total for all outputs:71mA
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.
VDD = 4.5V
IOL = 100A2
2. Capacitive loading on Ports 0 and 2 may cause spurious noise to be superimposed on the VOLs of ALE and Ports 1 and 3. The noise
due to external bus capacitance discharging into the Port 0 and 2 pins when the pins make 1-to-0 transitions during bus operations.
In the worst cases (capacitive 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.
