<p>PURPOSE:To provide a printing head driving IC capable of achieving the miniaturization and cost reduction of a printing head by reducing the number of flip-flop circuits and adapted to a printing head. CONSTITUTION:A first AND circuit part 30 is provided and flip flop circuits 20-1-20-32 are connected to the AND circuits of the first AND circuit part 30 in a ratio of one flip-flop circuit per two AND circuits. The odd number-th AND circuits of the AND circuits 30-1-30-3... can be operated when a DI.ENL signal is Low and the even number-th AND circuits of the AND circuits 30-2, 30-4... can be operated when the DI.ENL signal is High.</p> |
