ON Semiconductor MC74LCX574MELG Octal D-Type Flip-Flop with 3-State Outputs

The MC74LCX574MELG is a high-performance, octal D-type flip-flop integrated circuit from ON Semiconductor, designed for use in applications requiring a high-speed and low-power interface to communicate with bus-organized systems. This device is part of the LCX family, which is known for its 5V tolerant inputs, making it compatible with mixed-voltage systems.

Each flip-flop in the MC74LCX574MELG has a 3-state output, which means that besides the normal high and low logic levels, it can also be placed in a high-impedance state. This feature is particularly useful for bus-oriented applications, where multiple devices may need to share the same connection lines without interfering with each other.

The device is characterized for operation from -40°C to +85°C, making it suitable for industrial applications that require a broad operating temperature range. The MC74LCX574MELG comes in a 20-lead SOIC package, which is ideal for space-constrained applications while providing adequate thermal performance.

Key features of the MC74LCX574MELG include:

• Support for 2V to 3.6V V_CC operating voltage range, with 5V tolerant inputs.
• High-speed data transfer capability, with a typical t_PD of 4.5 ns at 3.3V.
• Low quiescent power dissipation, making it energy-efficient for battery-powered devices.
• Power-off high impedance inputs and outputs, which help prevent erroneous data transmission during power cycling.
• Support for live insertion and withdrawal, allowing for easy maintenance and upgrades without disrupting system operation.
• Multiple ground pins for minimal noise and ground bounce.

The MC74LCX574MELG is ideal for interfacing with high-speed microprocessors and can be used in a wide range of applications, including servers, telecommunications, networking equipment, and data storage systems. Its robust design ensures reliable operation in the most demanding environments, making it a preferred choice for designers looking for a dependable flip-flop solution.
