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=VCC.
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=VCC.
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=VCC.
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 (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.
