STMicroelectronics 74ACT574TTR Octal D-Type Flip-Flop
The 74ACT574TTR from STMicroelectronics is a high-speed CMOS octal D-type flip-flop integrated circuit that is designed to provide high-performance state storage in a wide array of digital applications. This device is a significant component in the realm of digital electronics, offering a reliable solution for data storage, data transfer, and signal buffering.
Encased in a TSSOP-20 package, the 74ACT574TTR ensures a compact footprint on the printed circuit board (PCB), making it an excellent choice for space-constrained applications. Its surface-mount design is optimized for automated assembly processes, which is advantageous for high-volume production environments.
Featuring eight edge-triggered D-type flip-flops, the 74ACT574TTR captures the state of each D-input at a precise moment determined by the clock cycle. Once captured, the data is available at the outputs until the next rising edge of the clock signal. This characteristic makes it suitable for implementing synchronous state machines, shift registers, and buffer registers.
The device operates with a wide supply voltage range from 4.5V to 5.5V, which allows it to be used in both 5V-tolerant legacy systems and more modern digital circuits. Additionally, the 74ACT574TTR boasts a high noise immunity and low power consumption, which is a hallmark of the advanced CMOS technology employed by STMicroelectronics.
Key features of the 74ACT574TTR include:
- Eight D-type flip-flops with single clock and output enable (OE) inputs
- Guaranteed output drive capability up to 24mA at the outputs
- High-speed performance, with typical clock-to-Q output times of only 6ns
- Low power dissipation with ICC reduced by 50%
- Bus-friendly outputs that do not load the bus when the output enable (OE) is inactive
- Latch-up performance exceeds 300mA, which provides robustness and reliability
- ESD protection tested to exceed 2000V
With its combination of speed, efficiency, and robustness, the 74ACT574TTR is an ideal choice for applications that require high-speed data manipulation and stable storage, such as computing systems, communication devices, and industrial control panels. Its compliance with JEDEC standards ensures compatibility with other JEDEC-compliant devices, making it a versatile component in the designer's toolkit.
