SN74BCT574DW Octal Edge-Triggered D-Type Flip-Flops

The SN74BCT574DW 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 features eight D-type flip-flops with 3-state outputs, making it an excellent choice for bus-oriented systems. It is part of the 'BCT family of products, which are known for their high drive and fast speeds, operating on a 4.5V to 5.5V VCC supply.

Each flip-flop in the SN74BCT574DW has a direct clear input and data input, and the device operates on the positive edge of the clock input signal. This means that when the clock input transitions from low to high, the data present at the data inputs is captured and held at the outputs until the next rising edge of the clock signal. The 3-state outputs allow the device to interface directly with and drive data buses with minimal power and propagation delay.

The SN74BCT574DW comes in a 20-pin SOIC package, which is widely used and suitable for surface-mount technology (SMT). The package is designed for optimal board space utilization, ensuring a compact footprint in end applications. The device features a fully buffered clock and data inputs, which provide stable operation and improved noise immunity.

Key features of the SN74BCT574DW include:

• Eight edge-triggered D-type flip-flops
• 3-state bus driving outputs
• Full parallel access for loading
• Buffered control inputs
• Operating voltage range of 4.5V to 5.5V
• High-drive outputs (-32-mA IOH, 64-mA IOL)
• High-impedance state during power up and power down
• Edge-triggered from a low-to-high transition
• Wide operating temperature range of -40°C to 85°C

The SN74BCT574DW is suitable for a variety of digital applications, including addressable registers, bus interfacing, and data storage. Its robust design and high-speed operation ensure reliable performance in demanding environments. Whether used in computing systems, communication infrastructure, or industrial electronics, the SN74BCT574DW is an excellent choice for designers seeking a reliable and efficient octal flip-flop IC.
