Abstract
A transmitting apparatus of simple circuit configuration is provided as having turn off time (cut off delay time) of an output transistor shortened. The potential of a low-level signal is inputted to an input terminal of a first transistor through a resistor. The potential of a high-level signal is inputted to an input terminal of a second transistor through a resistor. A control circuit is connected to the input terminals of the first and second transistors and when a high-level signal is to be transmitted to the communication line, the control circuit enters a high-impedance state with respect to the input terminal of the first transistor and outputs a low-level signal to the input terminal of the second transistor. When a low-level signal is to be transmitted over the communication line, the control circuit outputs a high-level signal to the input terminal of the first transistor and develops a high-impedance state with respect to the input terminal of the second transistor.
