Print head and liquid ejecting apparatus

A liquid ejecting apparatus comprising:

• a drive signal output circuit outputting a drive signal;
• and
• a print head assembled to the liquid ejecting apparatus ejecting liquid with respect to a medium, wherein
• the print head assembled to the liquid ejecting apparatus ejecting the liquid with respect to the medium includes:
• a first ejecting portion ejecting the liquid by being supplied with a high voltage signal changing in voltage value;
• a second ejecting portion ejecting the liquid by being supplied with the high voltage signal;
• a first ejecting portion group having a plurality of ejecting portions including the first ejecting portion and the second ejecting portion;
• a first switch switching between whether or not to supply the high voltage signal to the first ejecting portion in accordance with a low voltage logic signal having a maximum voltage value lower than a maximum voltage value of the high voltage signal and changing in voltage value;
• a second switch switching between whether or not to supply the high voltage signal to the second ejecting portion in accordance with the low voltage logic signal;
• a switch group having a plurality of switches including the first switch and the second switch;
• a memory;
• a high voltage signal input terminal to which the high voltage signal is input;
• and
• a low voltage logic signal input terminal to which the low voltage logic signal is input, and
• the print head has:
• a first mode in which the print head executes reading processing of reading information stored in the memory and does not execute ejection control processing of controlling whether or not to supply the high voltage signal to the first ejecting portion group by switching the switch group in accordance with an input signal input from the low voltage logic signal input terminal, and
• a second mode in which the print head does not execute the reading processing and executes the ejection control processing in accordance with the input signal.
