TLV3702-Q1: operation at below minimum voltage

Part Number: TLV3702-Q1

Hi

I would like to know how the device behaves when the input voltage is below 2.7V. (This is minimum voltage at single supply)

Does this device output low level ? or high level ? or unknown? 

Our customer is concerned how this device operates when it startup.  Because some other device outputs the glitch during startup until it reaches minimum voltage.
