Abstract
A signal receiver and a signal transceiver are provided, which may avoid unnecessary leakage current. The signal receiver includes a termination switch pair, a first resistor, a second resistor, and a pull-down circuit. The termination switch pair receives an operation power supply. The termination switch pair has a common control end. The first resistor is coupled between a first signal input end and the common control end. The second resistor is coupled between a second signal input end and the common control end. The pull-down circuit is coupled between the common control end and a reference voltage end. The pull-down circuit determines whether to pull down a first control voltage on the common control end to a reference voltage according to a power-on state or a power-off state of the signal receiver.
