Abstract
The present invention provides a receiver device having multiple voltage supplies that allows the output stage of the receiver device to go to a safe state whenever its voltage is disconnected or powered-down, independent of any of its normal control circuits. Furthermore, the isolation of the multiple voltage supplies provides a low skew at the output of the receiver device.
