NOTES:
1. Typical ratings are based on a limited number of samples taken from early manufacturing lots and are not guaranteed. The values listed are
at room temperature, 5V.
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 > 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.
3. Capacitive loading on ports 0 and 2 may cause the V
OH
on ALE and PSEN to momentarily fall below the 0.9V
CC
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
IN
is approximately 2V.
5. I
CCMAX
at other frequencies is given by:
Active mode: I
CCMAX
= 0.94 X FREQ + 13.71
Idle mode: I
where FREQ is the external oscillator frequency in MHz. I
CCMAX
is given in mA. See Figure 13.
6. See Figures 14 through 17 for I
CC
test conditions.
7. C
IO
applies to ports 1 through 6, AFLAG, BFLAG, XTAL1, XTAL2.
