NOTES:
1. Typical ratings are not guaranteed. The values listed are 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
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 V specification when the
address bits are stabilizing.
4. See Figures 29 through 32 for I
CC
test conditions.
Active mode:
I
CC
= fclk *0.1 mA/MHz + 0.3 mA (1.8 V). See Figure 27
Active mode:
I
CC
= fclk *0.25 mA/MHz + 0.7 mA (3.3 V)
Idle mode:
I
CCI
= fclk *0.04 mA/MHz + 0.2 mA
5. Load capacitance for port 0, ALE, and PSEN = 100 pF, load capacitance for all other outputs = 80 pF.
6. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
OL
per port pin:
10 mA
Maximum I
per 8-bit port:
20 mA
Maximum total I
for all outputs:
40 mA
If I
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
7. ALE is tested to V
OH1
, except when ALE is off then V
OH
is the voltage specification.
8. Pin capacitance is characterized but not tested. Pin capacitance is less than 15 pF.
