STMicroelectronics 74ACT273TTR Octal D-Type Flip-Flop

The 74ACT273TTR from STMicroelectronics is a high-speed CMOS octal D-type flip-flop integrated circuit, designed for use in applications requiring the capturing and storage of data. This device is particularly useful in systems where a stable data buffer is needed, such as in data acquisition, multiplexing, and various types of registers. With its advanced silicon-gate CMOS technology, the 74ACT273TTR offers robust performance and is compatible with most 16-pin logic devices.

The 74ACT273TTR features eight edge-triggered D-type flip-flops with individual D inputs and Q outputs. The flip-flops are controlled by a common clock (CP) and a global clear (MR) input. When the MR input is held low, all flip-flops are simultaneously cleared, regardless of the clock input condition. This allows for rapid initialization of the system when required. The flip-flops capture data on the rising edge of the clock, ensuring reliable and predictable data storage.

This product is supplied in a TSSOP20 package, which is optimized for reduced space on PCBs, making it an excellent choice for compact electronic designs. The package is also tape and reel packed (TTR suffix), which facilitates automated assembly processes and is ideal for high-volume production environments.

Key features of the 74ACT273TTR include:

• High-speed operation, ensuring quick response times in critical applications.
• Low power consumption, which is essential for energy-sensitive designs.
• Guaranteed output drive capability, providing reliable interfacing with other logic families.
• Wide operating voltage range of 4.5V to 5.5V, allowing for use in a variety of digital systems.
• Input and output levels compatible with TTL logic, ensuring easy integration into existing designs.

The 74ACT273TTR is characterized for operation from -40°C to +85°C, making it suitable for industrial applications where temperature extremes are common. Its performance and durability are assured by STMicroelectronics' commitment to high-quality standards, making it a dependable choice for designers seeking a reliable flip-flop solution.

Whether used in microprocessor systems, computer servers, or communication devices, the STMicroelectronics 74ACT273TTR provides the functionality and performance required for efficient data handling in complex electronic circuits.
