SN74LVTH574NSR Octal Edge-Triggered D-Type Flip-Flop

The SN74LVTH574NSR from Texas Instruments is a high-performance, octal edge-triggered D-type flip-flop designed for use in systems that require low-voltage operation and high-speed performance. This device is part of the LVTH family, which offers a wide operating voltage range and is optimized for 3.3V systems while maintaining 5V tolerant inputs.

The SN74LVTH574NSR flip-flops feature eight edge-triggered D-type flip-flops with 3-state outputs. These outputs can be used to interface with bus-structured systems, providing the capability to act as either a receiver or a driver. The device's 3-state outputs also allow for connection to a bus-structured system without the need for external pull-up resistors, saving board space and reducing component count.

One of the key features of the SN74LVTH574NSR is its support for bus hold, which retains the inputs' last state whenever the input goes to a high impedance. This prevents floating inputs and eliminates the need for external pull-up or pull-down resistors. The flip-flops are triggered on the low-to-high transition of the clock input signal, while a clear input is also provided to directly clear the flip-flop, ensuring flexibility and control in a variety of applications.

The device is housed in a compact 20-pin SOP (Small Outline Package) with a body size of 5.3 mm x 7.5 mm, making it suitable for space-constrained applications. The SN74LVTH574NSR operates over the industrial temperature range of -40°C to 85°C, ensuring reliable performance in harsh environments.

With its advanced features and robust design, the SN74LVTH574NSR is ideal for a range of applications, including telecommunications, computing, networking, and storage systems where high-speed, low-voltage operation is critical. Texas Instruments' commitment to quality ensures that the SN74LVTH574NSR meets the stringent requirements of modern electronic systems, providing engineers with a reliable and efficient solution for their design needs.
