This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect device reliability. Power dissipation is based on the maximum allowable die temperature and the thermal resistance of the package.

Operating I CC is measured with all output pins disconnected; XTAL1 driven with T CLCH , T CHCL = 5 ns (see Figure 60), V IL = V SS + 0.5V, V IH = V CC - 0.5V; XTAL2 N.C.; EA = RST = Port 0 = V CC . I CC would be slightly higher if a crystal oscillator used (see Figure 57). 2. Idle I CC is measured with all output pins disconnected; XTAL1 driven with T CLCH , T CHCL = 5 ns, V IL = V SS + 0.5V, V IH = V CC - 0.5V; XTAL2 N.C; Port 0 = V CC ; EA = RST = V SS (see Figure 58). 3. Power-down I CC is measured with all output pins disconnected; EA = V CC , PORT 0 = V CC ; XTAL2 NC.; RST = V SS (see Figure 59). 4. Capacitance loading on Ports 0 and 2 may cause spurious noise pulses to be superimposed on the V OLS 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 100 pF), the noise pulse on the ALE line may exceed 0.45V with maxi V OL peak 0.6V. A Schmitt Trigger use is not necessary. 5. Typical values 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, I OL must be externally limited as follows: Maximum I OL per port pin: 10 mA Maximum I OL per 8-bit port: Port 0: 26 mA Ports 1, 2 and 3: 15 mA Maximum total I OL for all output pins: 71 mA If I OL exceeds the test condition, V OL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions. Figure 57.
