NOTES FOR DC ELECTRICAL CHARACTERISTICS
1.
The operating supply current is measured with all output disconnected;
XTAL1 driven with t

f
= 5ns; V

2.
The IDLE MODE supply current is measured with all output pins disconnected;

3.
The POWER-DOWN MODE supply current is measured with all output pins disconnected;

IL
= V
SS
+0.5V; V
IH
=V
CC
-0.5V; XTAL2 not connect; /EA= Port0=V
DD
;
4.
Port 1, 2, 3, and 4 sources a transition current when they are being externally driven from HIGH to LOW. The transition current reaches its
maximum value when V
IN
is approximately 2V.
5.
Capacities loading on port 0 and 2 may cause spurious noise to be superimposed on V
OL
of ALE and port 1, 3, and 4. The noise is due to external
bus capacitance discharging into port 0 and port 2 pins when these pins make 1-to-0 transitions during bus operations. In the worst cases
(capacities 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.
6.
Under steady state (non-transient) conditions, IOL must be externally
Limited as follows:
Maximum IOL per pin (use sign pin only) : 10mA
Maximum IOL per 8-bit port :
port 0 : 26mA
port 1,2,3 : 15mA
Maximum total IOL for all output pins : 71mA
If IOL exceeds the condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions.
Specifications subject to change without notice contact your sales representatives for the most recent information.
