74ALVC574BQ,115

Logic - Flip Flops

74ALVC574BQ,115 is part of the 74ALVCH logic family, and is a low-voltage, high-performance CMOS data storage device. This device features octal D-type flip-flops that accept data on the low-to-high clock transition and present the data in 8-bit parallel format on the four data output lines (Q0-Q3). The edge-triggered flip-flops have a direct-clear input and independent set inputs, making them ideal for the implementation of a direct parallel data storage function.

Application Field

The 74ALVC574BQ,115 can be used to implement a variety of logic functions including memory and register files, arithmetic logic units, multiplexers/demultiplexers, multipliers/dividers, signal modulators/demodulators, translate/convert logic and generalize functions. It is an ideal choice for CMOS logic applications that require wide operating temperature range and low quiescent current.

Working Principle

Each of the octal flip-flops has a dedicated data input (D), a direct-clear input (CLR) and a set-enable input (S). When the positive-going edge of the clock (CLK) occurs, the data present at the D input is stored in the flip-flop, and can be read at the Q output. The CLR and S inputs are used to reset and set the Q output logic levels, respectively. Also, the Q output can be disabled by using the enable input (EN).

Advantages

The 74ALVC574BQ,115 provides customers with an improved ability to satisfy specialized applications when compared to traditional IC technologies. This device has a wide operating voltage range.

• High-speed operation with low stand-by current.
• Doubly safe operation with enhanced noise margin.
• Higher reliability and better thermal stability.
• Compatibility with industry standard logic levels.

Conclusion

The 74ALVC574BQ,115 is a high-performance CMOS data storage flip-flop that is well-suited for a range of applications. This device features octal D-flip-flops that are edge-triggered and clocked by a low-to-high clock transition. It also has independent set/reset inputs and enable/disable functionality. This device offers improved reliability, better thermal stability, increased noise margin and compatibility with industry standard logic levels.
