Dedicated Input Pins
If a dedicated input pin is connected to a power supply different from the supply that Vcc is connected to, a resistor
(approximately 1k ohm) should be added between the input pin and the connected power supply. However, if the
dedicated input pin voltage is higher than Vcc, latch up could occur. A resistor is not required when using a Vcc
voltage equal or greater than the voltage of the dedicated input pin.
