SN74LVT574DW Octal Edge-Triggered D-Type Flip-Flops
The SN74LVT574DW is a high-performance, octal edge-triggered D-type flip-flop integrated circuit designed and manufactured by Texas Instruments. This device is part of the LVT family, which stands for Low-Voltage BiCMOS Technology. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers in a wide range of digital applications.
With its 3.3V operating voltage, the SN74LVT574DW is optimized for low-voltage operations, providing a robust interface between 3.3V and 5V systems. This makes it an ideal choice for interfacing with microprocessors, microcontrollers, and other digital systems that operate at lower voltages, while still maintaining compatibility with 5V TTL logic.
The device features eight D-type flip-flops with a direct clear input. It is capable of storing eight bits of data. Each flip-flop is triggered on the rising edge of the clock input signal, allowing for synchronous data transfer. The clear function is synchronous, meaning that the output of the flip-flops can be cleared by a high level on the clear input while the clock is high.
One of the key advantages of the SN74LVT574DW is its high drive capability, which allows for driving heavy loads without the need for additional buffer components. The outputs can also be placed in a high-impedance state, which is useful in bus-oriented applications.
The SN74LVT574DW comes in a wide-body SOIC (Small Outline Integrated Circuit) package, which is denoted by the 'DW' suffix in its part number. This package type is suitable for surface mount technology (SMT), offering a compact footprint while still providing ease of handling and manufacturing.
As with many Texas Instruments products, the SN74LVT574DW is characterized for operation from -40°C to 85°C, ensuring reliable performance across a broad range of environmental conditions. This makes it a versatile solution for industrial, commercial, and even some harsh-environment applications.
In summary, the SN74LVT574DW from Texas Instruments is a reliable and efficient solution for data storage and transfer applications requiring low-voltage operation and compatibility with TTL logic levels. Its robust design and wide operating temperature range make it suitable for a variety of challenging environments and applications.
