ABSTRACT:
A logic signal transmitting circuit includes a CMOS inverter, a first transistor switch and an inverter. The CMOS inverter includes a p-type transistor and an n-type transistor and is configured for inverting an input signal. The first transistor switch is connected to an input of the CMOS inverter and controlled by the input signal. The inverter is connected between the p-type transistor and the first transistor switch, in which the inverter turns off the p-type transistor when the first transistor switch is turned on and the inverter turns on the p-type transistor when the first transistor switch is turned off.
