NXP 74LVC821APW: 10-bit D-type Flip-flop with 5V Tolerant Inputs/Outputs
The NXP 74LVC821APW is a high-performance, low-voltage CMOS product which is part of the LVC family, offering a 10-bit D-type flip-flop with 5V tolerant inputs and outputs. It is designed to operate from a 2.7V to 3.6V power supply, making it suitable for interfacing with 5V logic levels while maintaining low voltage operation to conserve power in critical applications.
With its edge-triggered design, the 74LVC821APW captures data on the rising edge of the clock signal, ensuring precise timing and synchronization across all ten flip-flops. The device features a direct clear input (nCLR) which, when asserted low, will reset all ten bits to a low state, providing a quick and efficient way to clear the device's contents.
One of the key features of this product is its 5V tolerance on inputs and outputs, which allows for mixed-voltage system integration and provides greater design flexibility. This feature is particularly beneficial in environments where legacy 5V systems are being upgraded or interfaced with newer 3.3V logic components.
The 74LVC821APW is housed in a TSSOP20 package, which is known for its slim profile and space-saving footprint. This makes it an excellent choice for compact and densely populated PCB designs where board real estate is at a premium.
Additionally, this device supports bus hold on data inputs, which eliminates the need for external pull-up or pull-down resistors and simplifies board design. The bus hold circuitry maintains the last valid input state whenever the input goes to a high-impedance (Hi-Z) state, ensuring stable operation during inactive periods.
For applications that require high-speed data storage and retrieval, the NXP 74LVC821APW offers a robust solution with its fast propagation delays and high clock frequencies. Whether used in telecommunications, computing, or consumer electronics, this flip-flop provides the reliability and performance needed for today's digital logic circuits.
Overall, the NXP 74LVC821APW represents a smart choice for designers looking to bridge the gap between 3.3V and 5V systems while maintaining low power consumption, high speed, and compact packaging.
