Signal receiver and electronic apparatus including the same

A signal receiver for receiving a signal from an external device, the signal receiver comprising:

• first to fourth buffers each including a first input terminal and a second input terminal;
• a first input interface configured to output a first type signal between the first type signal and a second type signal to the first buffer;
• and
• second to fourth input interfaces configured to output the first type signal or the second type signal to the second to fourth buffers, respectively,
• wherein two of the first to fourth buffers operate in response of operation in a first type mode based on the first type signal, and three of the first to fourth buffers operate in response of operation in a second type mode based on the second type of signal.

An electronic apparatus comprising a signal receiver for receiving a signal from an external device,

• wherein the electronic apparatus comprising:
• a first input interface configured to output a first type signal between the first type signal and a second type signal;
• second to fourth input interfaces configured to output the first type signal or the second type signal;
• a first buffer electrically connected to the first input interface and the second input interface;
• a second buffer electrically connected to the second input interface and the third input interface;
• a third buffer electrically connected to the third input interface and the fourth input interface;
• and
• a fourth buffer electrically connected to the fourth input interface and the second input interface.
