ON Semiconductor MC74LCX574DTR2 Octal D-Type Flip-Flop

The MC74LCX574DTR2 from ON Semiconductor is a high-performance, octal D-type flip-flop integrated circuit designed for use in advanced communication, computing, and control systems where low voltage operation with high speed and low power consumption is essential. This device is part of the LCX family, which is fabricated with an advanced CMOS technology to achieve superior switching performance with high immunity to noise.

Featuring a 3.3V power supply voltage, the MC74LCX574DTR2 is ideal for interfacing with 5V systems, as it is equipped with 5V tolerant inputs, which can be driven from either 3.3V or 5V devices. This flexibility makes it suitable for mixed-voltage applications and enables it to support the migration from 5V to 3.3V systems without the need for additional level shifters.

The device offers eight edge-triggered flip-flops with individual D-type inputs and outputs. The flip-flops capture the state of their respective D-inputs on the rising edge of the clock, providing a reliable and predictable data storage and transfer mechanism. Each flip-flop has a separate 3-state output control input, which allows for the selective placement of outputs into a high-impedance state. This feature is particularly useful for implementing bus-oriented systems, as it allows multiple devices to share a common data bus without conflict.

Furthermore, the MC74LCX574DTR2 ensures data integrity with its built-in power-up 3-state control and ground bounce protection. The device is offered in a TSSOP-20 package, which is not only space-saving but also conducive to efficient PCB layout and thermal management.

With its fast propagation delay and output transition times, the MC74LCX574DTR2 is optimized for high-speed data transmission, which is critical in modern digital systems. It is characterized for operation from -40°C to +85°C, ensuring reliable performance across a wide range of environmental conditions.

Whether you're designing next-generation microprocessors, memory interfaces, or portable electronics, the ON Semiconductor MC74LCX574DTR2 offers a blend of speed, power efficiency, and robustness that can help elevate your system's performance.
