8.3.1 Logic Inputs

TI recommends using a high-value pullup resistor when logic inputs are pulled up to VDD. This resistor limits the current to the input in case an overvoltage event occurs. Logic inputs are nSLEEP, MODE, PHASE, and ENABLE. Voltages higher than 7 V on any logic input can cause damage to the input structure.
