The PI74FCT821BTP consists of ten D-type flip-flops with a common clock and output enable. Data is latched into the flip-flops on the positive-going edge of the clock pulse. The 3-state outputs are controlled by an output enable (OE) input. When OE is low, the outputs are enabled; when OE is high, the outputs are in the high-impedance state, effectively disconnecting the register from the bus. The device operates from a 5V power supply and is designed to minimize ground bounce, which helps to reduce noise and improve signal integrity in high-speed systems. Its combination of speed, buffering capability, and 3-state outputs makes it suitable for various applications where reliable data transfer and isolation are critical.
