NOTES:
1. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any conditions other than those described in the AC and DC Electrical Characteristics section
of this specification is not implied.
2. This product includes circuitry specifically designed for the protection of its internal devices from the damaging effects of excessive static
charge. Nonetheless, it is suggested that conventional precautions be taken to avoid applying greater than the rated maxima.
3. Parameters are valid over operating temperature range unless otherwise specified. Voltages are with respect to V
SS
unless otherwise noted.

NOTES:
1. Typical ratings are based on a limited number of samples from early manufacturing lots, and not guaranteed. Values are room temp., 5V.
2. Capacitive loading on ports 0 and 2 may cause spurious noise to be superimposed on the V
OL
s of ALE and the other ports. 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, 3, 4, 5 and 6 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
CC
MAX at other frequencies is given by:
Active mode: I
CC
MAX = 0.94 X FREQ + 13.71
Idle mode: I
where FREQ is the external oscillator frequency in MHz. I
CC
MAX is given in mA. See Figure 20.
6. See Figures 21 through 24 for I
CC
test conditions.
7. C
IO
applies to ports 1 through 6, IDS, ODS, AFLAG, BFLAG, XTAL1, XTAL2.
