Abstract: A data communications transceiver for transmitting signals to and from a medium has an output driver connected to the medium through a series connected first pair of diodes and a receiving transistor amplifier whose input is connected to the medium and whose output leads are each connected to a separate one of a second pair of diodes, whereby a low input capacitance is achieved.

Abstract: A data communications transceiver for transmitting signals to and from the communicating medium, with the transceiver including an input terminal, a short time constant differentiator connected to the input terminal to differentiate signals applied thereto, a Schmitt trigger supplied with the output of the short time constant differentiator for producing a corresponding square wave output signal, a first driver supplied with the square wave output of the Schmitt trigger for supplying it to the communicating means, amplifying means for receiving signals from the communicating medium and for producing an amplified output therefrom, a second short time constant differentiator supplied with the output of the amplifying means and for supplying it to a second Schmitt trigger for producing a corresponding second square wave signal, and a second driver supplied with a second square wave signal for supplying it to an output terminal.
