The PI74FCT374TQA consists of eight D-type flip-flops with a common clock input. The data at the D inputs is transferred to the outputs on the positive-going edge of the clock pulse. The outputs are tri-state, meaning they can be in a logic high, logic low, or high-impedance state. The output enable (OE) input controls the state of the outputs. When OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state. The device operates from a single 5V power supply. The device's high-speed performance and tri-state outputs make it ideal for use in high-speed memory systems and bus interface applications where data contention must be avoided. Its robust design ensures reliable operation over a wide range of temperature and voltage conditions.
