Notes 1: VCC = 2.7 V to 5.5 V, VSS = 0 V, and Ta = –20
°C to 85 °C (Ta = –40 ° C to 85 °C for extended
operating temperature range version), unless otherwise noted.
For the clamping diodes of port P4, refer to (4) Level Shift Ports in Section 1.10.3 I/O Ports.
2: When voltage is applied through a resistor, current I of 1 mA or less maintains VI > VCC.
For this circuit, refer to Figure 1.10.11 Port P4 and P5 Circuit.
