Abstract
A half-duplex communication system may include one or more low-voltage differential signaling half-duplex transceivers. Each transceiver may include a plurality of input terminals receiving a plurality differential data signals, an input driver transferring the differential data signals from differential transmission lines through output terminals, and an output driver transferring the differential data signals from the input terminals through the differential transmission lines and out to one of the first and second transceivers via the non-inverse and inverse transmission lines. The differential data signals may be transferred in response to the differential data signals at the input terminals and at the output terminals of the input driver. Each transceiver may include a pre-driver configured to shift a reference voltage level of differential data signals input thereto from the input terminals and which are to be supplied to the output driver therefrom.
