The 74FCT821HCTQ is a high-speed octal flip-flop IC (Integrated Circuit) component manufactured by various semiconductor companies, including Fairchild Semiconductor and Texas Instruments. This component is built using advanced CMOS technology, incorporating Schottky diode clamping to achieve high-speed operation. Here's an overview of the 74FCT821HCTQ and its key features:
1. Function: The 74FCT821HCTQ is an eight-bit D-type flip-flop with eight master-slave flip-flops on a single chip. It is a synchronous device with the ability to latch data on the rising edge of the clock signal.
2. Data Synchronization: The IC's flip-flops are designed for synchronizing data with the input clock signal. It guarantees stable and reliable operation by sampling input data precisely at the clock's rising edge.
3. Output Enable: The 74FCT821HCTQ features an active-high output enable (OE\) pin. When this pin is set to a logical low (0V), the outputs become high-impedance state, allowing other devices to control the bus without any interference. On the other hand, when OE\ is high (above 2V), the outputs function normally.
4. Asynchronous Clear: This IC provides an asynchronous clear (CLR\) input for clearing the flip-flop stages
