Notes for DC Electrical Characteristics
1. Operating ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5 ns (see Figure 13), VIL = VSS + 0.5V,
VIH = VCC – 0.5V; XTAL2 N.C.; EA = RST = Port 0 = VCC. ICC would be slightly higher if a crystal oscillator used (see NO TAG).
2. Idle ICC is measured with all output pins disconnected; XTAL1 driven with TCLCH, TCHCL = 5ns, VIL = VSS + 0.5V, VIH = VCC–0.5V; XTAL2
N.C; Port 0 = VCC; EA = RST = VSS (see Figure 11).
3. Power Down ICC is measured with all output pins disconnected; EA = VSS, PORT 0 = VCC; XTAL2 NC.; RST = VSS (see NO TAG).
4. 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 operation. In the worst
cases (capacitive loading 100pF), the noise pulse on the ALE line may exceed 0.45V with maxi VOL peak 0.6V. A Schmitt Trigger use is not neces-
sary.
5. Typicals are based on a limited number of samples and are not guaranteed. The values listed are at room temperature and 5V.
6. Under steady state (non–transient) conditions, IOL must be externally limited as follows:
Maximum IOL per port pin:
Maximum IOL per 8–bit port:
Port 0:
Ports 1, 2 and 3:
Maximum total IOL for all output pins:
10 mA
26 mA
15 mA
71 mA
If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test condi-
tions.
