LMK1C1104: Internal clamping diodes

Part Number: LMK1C1104
Other Parts Discussed in Thread: CDCV304, , CDCE949

Hello,

Does the clock input (general all inputs) provide clamping diode(s) to Vdd? Currently we are powering the clock buffer via electronic switch (+3.3V switched). The clock input itself is derived from circuitry powered directly with our main supply voltage (+3.3V) - so the voltage before the switch. With another clock buffer (CDCV304) we face the issue of feeding power via input pin due to input clamping diode (see figure below). According datasheet of LMK1C1104 it is not obvious if the inputs provide clamping diodes.

Thanks in advance!
