The QS74FCT520ATQ is an integrated circuit (IC) component that belongs to the QS series of FCT (Fast CMOS) logic devices. It is a 8-bit counter/shift register with asynchronous clear, which means it can perform both counter and shift register functions depending on the mode of operation.
Key features of the QS74FCT520ATQ include:
1. Eight-Bit Counter/Shift Register: The IC has eight flip-flops that can operate as a counter or a shift register depending on the configuration. It can count up or down based on the inputs and control signals applied.
2. Asynchronous Clear: The IC provides an asynchronous clear feature which allows the user to reset the counter/shift register to a known state using the CLEAR input pin. This pin can be activated at any time, regardless of other input conditions.
3. High-Speed Operation: The QS74FCT520ATQ is designed for high-speed operation, making it suitable for applications where fast data processing is required. It operates at a speed of up to 250MHz, enabling efficient data handling.
4. Low Power Consumption: Despite its high-speed operation, the IC is designed to consume low power, making it suitable for battery-powered devices or applications where power efficiency is crucial.
5. Wide Supply Voltage Range: The QS74FCT520ATQ can operate within a wide supply voltage range of 4.5V to 5
