How does LVTC logic provide “live insertion” protection?

LVTC’s inputs and outputs are designed with power-up/down control circuits, which senses the device’s Vcc supply voltages and put the inputs/outputs in high-impedance during the power up/down stages of live insertion/extraction. This will avoid the backflow of damaging current into the device and through the device to other components, and prevent driver conflict. Application Note 62 for more details.
