Notes:
1.
ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL= 5 ns, VIL= VSS + .5 V, VIH= VCC –.5 V; XTAL2
N.C. ; EA= RST= Port 0= VCC. ICC would be slighty higher if a crystal oscillator used.
Idle ICC is measured with all output pins disconnected ; XTAL1 driven with TCLCH, TCHCL= 5 ns, VIL= VSS + 5 V, VIH= VCC –.5 V ;
XTAL2 N.C; Port 0= VCC; EA= RST= VSS.
Power Down ICC is measured with all output pins disconnected; EA= PORT 0= VCC; XTAL2 N.C. ; RST= VSS.
Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the VOLS of ALE and Ports 1 and 3. 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 100 pF), the noise pulse on the ALE line may exceed 0.45 V may exceed 0,45 V with maxi
VOL peak 0.6 V. A Schmitt Trigger use is not necessary.
