Abstract
PURPOSE: To decrease the number of the component parts and to realize a miniature size as well as high reliability for the switch circuit by securing a connection of the common terminal to the zero-volt line via the resistance and then drawing outthe output signals across the resistance.
CONSTITUTION: The low-frequency signal is applied to output terminal B of the TTL or DTL integrated circuit, and at the same time the level control signal is applied to input terminal A. Then the common terminal is connected to the zero- volt line via resistanced 4. the output signals are drawn out across resistance 4. Thus, the number of the component parts can be decreased with enhanced reliability.
