Whether the SN74LVC2G74QDCURQ1 will be damaged in this mode, and whether there is a protection loop such as an input current limiting resistor inside the chip.

SN74LVC2G74QDCURQ1 supply voltage 5V, CLK input high level 6.3V, will the chip be damaged in this mode? In addition, is there a protection loop such as an input current limiting resistor inside the chip?

The absolute maximum ratings allow 6.5 V, so the device will not be damaged.

The recommended operating conditions allow only 5.5 V, so there is no guarantee that the flip flop actually works with that input voltage. (In practice, it will probably work.)

There are no ESD protection diodes between the inputs and VCC, so no current will flow, and no resistor is necessary.
