SN74LVTH574DWR Octal Edge-Triggered D-Type Flip-Flops

The SN74LVTH574DWR from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop integrated circuit designed for use in a wide range of digital applications. This device is part of the LVTH family, which means it operates at low voltage while maintaining high tolerance levels, ensuring compatibility with various modern systems.

Encased in a robust 20-pin SOIC package, the SN74LVTH574DWR is characterized by its 3-state outputs, which allow for connection to common data lines or bus-organized systems. This feature is particularly useful for memory address latching, interface buffering, and data storage, which are essential functions in complex digital systems.

One of the key attributes of the SN74LVTH574DWR is its support for mixed-mode signal operation, which means it can handle 5V input and output in a 3.3V environment. This allows for seamless integration in systems that operate on different voltage levels without the need for additional level-shifting hardware.

The device boasts an impressive performance with a -40°C to 85°C operating temperature range, making it suitable for industrial applications that require reliable operation under varying environmental conditions. Additionally, the SN74LVTH574DWR has a balanced propagation delay and transition times, which ensures high-speed data transfer and minimizes system delays.

Other features include:

• Edge-triggered D-type inputs with a direct clear (CLR) input
• Output control (OC) and complementary outputs to provide true and inverted data
• Maximum operating frequency of 240 MHz, which is ideal for high-speed applications
• Low power consumption, with a typical ICC of only 0.8 mA
• Latch-up performance exceeds 500 mA per JESD 17, ensuring robust operation
• ESD protection exceeds JESD 22, safeguarding the device from electrostatic discharges

Overall, the SN74LVTH574DWR is a versatile, high-speed flip-flop that is well-suited for a range of digital applications, from telecommunications to computing systems, where data integrity, speed, and reliability are paramount. Its compatibility with both 3.3V and 5V signals makes it a highly adaptable component for mixed-voltage designs.
