TPD12S520: HDMI/HDP Voltage staying low/high

Part Number: TPD12S520

Hello E2E,

I am using the TPD12S520DBTR part to protect the HDMI inputs from ESD.  When an HDMI cable is attached It is going to the normal 3.3V but when the cable is disconnected the HDP does not go below 2.5V.  It is at 0V if the unit is powered off and 0 Volts until a cable is plugged in with power on.   Is there a reason why this is not going to 0V when the cable is disconnected with power on?

Thank you very much!

Russell
