Product Overview: MC74LCX574DWR2G

The MC74LCX574DWR2G is a high-performance, octal D-type flip-flop with a clear function, designed and manufactured by ON Semiconductor. This advanced integrated circuit is part of the LCX family, which is known for its low voltage operation and compatibility with 5V tolerant inputs. This makes the MC74LCX574DWR2G an ideal choice for interfacing with legacy 5V systems while operating at a lower voltage, thus reducing power consumption.

The device features an 8-bit flip-flop with 3-state non-inverting outputs for bus-oriented applications. Each flip-flop is controlled by a clock (CK) input and an output enable (OE) input. The clear (CLR) input can reset all the flip-flops to a low level, ensuring that the device starts in a known state upon power-up or during a system reset. The flip-flops capture the data present on their inputs when the clock input is transitioned from low to high.

The MC74LCX574DWR2G operates at a voltage range of 2.3V to 3.6V, which allows for lower voltage operation and reduced power consumption without sacrificing speed. This makes it suitable for battery-powered and portable applications where power efficiency is crucial. The device also supports 5V I/O tolerance, which enables it to interface with 5V systems without the need for additional level shifting hardware, simplifying design and reducing component count.

Packaged in a 20-pin SOIC wide body (7.5mil), the MC74LCX574DWR2G is designed for surface-mount technology, allowing for compact PCB layouts. It features a propagation delay of approximately 5.5ns at 3.3V, contributing to its high-speed performance. This product is fully specified for partial-power-down applications using Ioff, which helps prevent damaging current backflow through the device when it is powered down.

The MC74LCX574DWR2G is an excellent choice for system designers who require a fast, low-power, and 5V tolerant octal flip-flop. Its features make it suitable for a wide range of applications, including communication systems, data processing, industrial control, and any system that bridges between different voltage domains.
