NOTES FOR DC ELECTRICAL CHARACTERISTICS
1. The operating supply current is measured with all output disconnected;
XTAL1 driven with t_r = t_f = 5ns; V_IL = V_SS+0.5V; V_IH=V_CC-0.5V; XTAL2 not connect;/EA=RST=Port0=V_CC.
2. The IDLE MODE supply current is measured with all output pins disconnected; XTAL1 driven with t_r = t_f = 5ns; V_IL = V_SS+0.5V;
V_IH=V_CC-0.5V; XTAL2 not connect;/EA= Port0=V_CC.
3. The POWER-DOWN MODE supply current is measured with all output pins disconnected; VIL = V_SS+0.5V; V_IH=V_CC-0.5V; XTAL2 not
connect; /EA= Port0=V_CC.
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.
