NOTES:
(see next page)
1. The pull-up structures on Port A0–7 can be disabled by software, they are automatically
enabled by each reset.
2. The pull-up structures on Port A consist of enabled PMOS devices. For input voltages near
V_SS they act like a constant current source.
3. A simple protection can be built with a series resistor: R > V_MAX /I_INJ. The sum of currents
during multiple injection should be limited below the maximum values for a single pin:
R > (V_MAX /I_INJ)•(number of pins).
Positive injection current can raise the supply voltage (V_DD). Care must be taken in the ap-
plication to ensure votages do not exceed the maximum ratings.
Characterized on the HC805PV8 and HC05PV8.
