Recoding element substrate, recording head equipped with the same, recording head cartridge, and recording apparatus
Abstract:
A recording element substrate which is provided with a first recording element group and a second recording element group, each group including a plurality of recording elements. The recording element substrate includes a first terminal configured to input a data signal, a second terminal configured to input a latch signal, a shift register configured to receive the data signal input from the first terminal, a first latch circuit configured to latch data stored in the shift register based on the latch signal of a first pulse width input from the second terminal, a second latch circuit configured to latch the data stored in the shift register based on the latch signal of a second pulse width which is shorter than the first pulse width of the latch signal input from the second terminal, a first driving circuit configured to control driving of the recording elements included in the first recording element group based on a signal output from the first latch circuit, and a second driving circuit configured to control driving of the recording elements included in the second recording element group based on a signal output from the second latch circuit.
