Liquid discharge head

A liquid discharge head, comprising:

• a plurality of discharging modules having a discharging drive element and a discharging heater electrically connected to the discharging drive element;
• a plurality of circulating modules having a circulating drive element and a circulating heater electrically connected to the circulating drive element, the circulating modules being arranged in pair with the discharging modules, and a number of the circulating modules being the same as a number of the discharging modules;
• a latch circuit for latching a data signal including selection information for selecting each of the plurality of discharging modules and the plurality of circulating modules;
• and
• a control unit for selectively controlling a first set of circulating modules or a second set of circulating modules among the plurality of circulating modules based on a count value of edges of latch signals producing latch timings for the latch circuit to latch the data signal, the second set of circulating modules arranged in a different placement area than the first set of circulating modules.
