1) Capacitive loading on ports 0 and 2 may cause spurious noise pulses to be superimposed on the
V
OL
of ALE
and port 3. The noise is due to external bus capacitance discharging into the port 0 and port 2 pins when these
pins make 1-to-0 transitions during bus operation. In the worst case (capacitive loading > 100 pF), the noise
pulse on ALE line may exceed 0.8 V. 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.
2) Capacitive loading on ports 0 and 2 may cause the
V
OH
on ALE and PSEN to momentarily fall below the
0.9
V
CC
specification when the address lines are stabilizing.

(power-down mode) is measured under following conditions:
EA = RESET = Port 0 = Port 6 =

8) Overload conditions occur if the standard operating conditions are exceeded, ie. the voltage on any pin
exceeds the specified range (i.e.
V
OV
>
V
CC
+ 0.5 V or
V
OV
<
V
SS
- 0.5 V). The supply voltage
V
CC
and
V
SS
must
remain within the specified limits. The absolute sum of input currents on all port pins may not exceed 50 mA.
9) Not 100% tested, guaranteed by design characterization
10)The typical
I
CC
values are periodically measured at
T
A
= +25 藲C and
V
CC
= 5 V but not 100% tested.
11)The maximum
I
CC
values are measured under worst case conditions (
T
A
= 0 藲C or -40 藲C and
V
CC
= 5.5 V)
