For termination regulators, when a voltage that does not exceed the VTT_IN voltage is supplied to the VTT pin during standby (VTT output OFF), does current flow to the VTT pin?
The VTT pin will show high impedance when the VTT output is OFF. And when a voltage not exceeding the VTT_IN voltage is supplied, a minute leakage on the order of nA flows to ground.
