摘要： A stable operation is realized without any malfunction of a driver even under a voltage condition that a supplied voltage is 3.3 V or lower. For this purpose, in an ink-jet printhead having an ink orifice for discharging ink, a plurality of heat generation elements for generating heat energy used to discharge ink, and an ink channel which incorporates the heat generation elements and communicates with the ink orifice, a driver for driving the heat generation elements, and a logic circuit for controlling the driver are formed on a single board. The gate oxide film thickness of an enhancement NMOS transistor which forms the driver is larger than that of an enhancement NMOS transistor which forms the logic circuit.

摘要： A printhead has a plurality of printing elements and a drive circuit for driving the printing elements aligned in a predetermined direction on an element board. The printhead is provided with a Schmitt trigger having hysteresis properties that give different threshold values to the rising and falling edges of a waveform of a logic signal (HE, LT, CLK, DATA) input into the drive circuit. The Schmitt trigger is provided with means for adjusting the length of the delay at the rising and falling edges of the input waveform signal, so that the speed of data transmission to the printhead can be increased even as the supply voltage is lowered.

摘要： Printhead substrate for inputting a data signal (DATA) in synchronization with a clock signal (CLK). The printhead substrate comprises: input terminals inputting the clock signal and data signal; shift registers inputting and maintaining the data signal in synchronization with the clock signal inputted from the input terminals; and a time lag adjuster arranged between an input terminal and the shift register to adjust a time lag of at least one of the clock signal or data signal. By virtue of adjusting the time lag by the time lag adjuster, setup time and hold time between the clock signal and the data signal inputted to the shift register is ensured.
