NOTES:
1. Typical ratings are not guaranteed. Values listed are based on tests conducted on limited number of samples at room temperature.
2. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
OL
s of ALE and ports 1 and 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 operations.
In the worst cases (capacitive loading > 100 pF), the noise pulse on the ALE pin 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. I
OL
can exceed these conditions provided
that no single output sinks more than 5 mA and no more than two outputs exceed the test conditions.
3. Capacitive loading on ports 0 and 2 may cause the V
OH
on ALE and PSEN to momentarily fall below the V
CC
–0.7 specification when the
address bits are stabilizing.
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
is approximately 2 V.
5. See Figures 60 through 63 for I
CC
test conditions and Figure 58 for I
CC
vs. Frequency
12-clock mode characteristics:
Active mode (operating):
I
CC
= 1.0 mA + 1.1 mA

FREQ.[MHz]
Active mode (reset):
I
CC
= 7.0 mA + 1.1 mA
FREQ.[MHz]
Idle mode:
I
CC
= 1.0 mA + 0.44 mA
FREQ.[MHz]
6. This value applies to T
= 0
°
C to +70
°
C. For T
= –40
°
C to +85
°
C, I
= –750 A.
7. Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
8. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin:
15 mA (*NOTE: This is 85
°
C specification.)
Maximum I
OL
per 8-bit port:
26 mA
Maximum total I
OL
for all outputs:
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.
9. ALE is tested to V
OH1
, except when ALE is off then V
OH
is the voltage specification.
