NOTES FOR DC ELECTRICAL CHARACTERISTICS
1.
The operating supply current is measured with all output disconnected;
XTAL1 driven with tr = tf = 5ns; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;
/EA=RST=Port0=VDD;
2.
The IDLE MODE supply current is measured with all output pins disconnected;
XTAL1 driven with tr = tf = 5ns; VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect;
/EA=Port0=VDD;
3.
The POWER-DOWN MODE supply current is measured with all output pins disconnected;
VIL = VSS+0.5V; VIH=VCC-0.5V; XTAL2 not connect; /EA= Port0=VDD;
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 VIN is approximately 2V.
5.
Capacities loading on port 0 and 2 may cause spurious noise to be superimposed on VOL 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
(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.
