4. Supply current values are for V
IH
min = VCC – 0.2 V and V
IL
max = 0.2 V with all output pins
unloaded and the on-chip pull-up MOSs in the off state.
5. When VCC = 3.0 V, V
IH
min = VCC – 0.2 V, and V
IL
max = 0.2 V.

Notes: 1. To protect LSI reliability, do not exceed the output current values in table 31.3.
2. When driving a Darlington transistor or LED, always insert a current-limiting resistor in the output
line, as show in figures 31.1 and 31.2.
