ABSTRACT:
A circuit of a multiplexing inkjet print system and a control circuit thereof for driving a plurality of jet orifices. A signal generating unit generates an enable signal according to a first clock signal and data. Then, a counter counts according to the enable signal to generate a plurality of time counting signals for N decoders, wherein N is a positive integer equal to or greater than 2. The N decoders decode the received time counting signal to generate N groups of start signals. Moreover, a shift register shifts data according to the enable signal and a second clock signal (or according to the first and the third clock signals) to generate i address signals, wherein i is a positive integer. Therefore, each of the heater circuits is driven under the control of an address signal and one of start signals of each group, thereby driving the corresponding jet orifice.
