ON Semiconductor MC74LVX574DTG Octal D-Type Flip-Flop with 3-State Outputs

The MC74LVX574DTG from ON Semiconductor is a high-performance, octal D-type flip-flop with 3-state outputs designed for use in applications requiring a high-speed and low-power interface to communicate with bus-organized systems. This integrated circuit is part of the LVX family, which is characterized by its 3.3V power supply and 5V tolerant inputs, making it compatible with mixed-voltage environments and ideal for interfacing with both 3.3V and 5V systems.

The device features eight edge-triggered flip-flops with individual D-type inputs and 3-state outputs. The flip-flops are triggered on the rising edge of the clock signal (CLK), allowing for synchronous operations. Each flip-flop has a separate Data (D) input and Output Enable (OE) control, which is used to place the outputs in either a normal logic state or a high-impedance state. The high-impedance state ensures that the outputs will neither load nor drive the bus when not in use.

The MC74LVX574DTG is packaged in a TSSOP-20 (Thin Shrink Small Outline Package) which provides a compact footprint and is suitable for surface mount technology (SMT). The device operates over a broad temperature range, making it well-suited for industrial and automotive applications that require robust performance under varying environmental conditions.

Key features of the MC74LVX574DTG include:

• Low voltage operation: 3.3V
• 5V tolerant inputs for interfacing with 5V logic levels
• High-speed performance: ≤ 4.5ns propagation delay time
• Low power consumption: 10µA maximum ICC
• Edge-triggered flip-flops for precise timing
• 3-state outputs for bus interfacing
• Industrial and automotive temperature range: -40°C to +85°C
• Lead-free and RoHS compliant

The MC74LVX574DTG is an essential component for designers looking to implement reliable data storage elements that can interface with high-speed buses while maintaining low power consumption. Its robust design and compatibility with mixed-voltage systems make it a versatile choice for a wide range of digital applications.
