The CD74ACT273SM is a high-speed CMOS Octal D-Type Flip-Flop with a clear feature, designed and manufactured by Texas Instruments. This integrated circuit is part of the 74ACT family, known for its significant improvements in speed over general CMOS logic while maintaining CMOS low power consumption.

Key Features

• Logic Type: Octal D-Type Flip-Flop with Clear
• IC Package Type: SOIC
• Number of Pins: 20
• Operating Temperature Range: -55°C to 125°C
• Supply Voltage Range: 4.5V to 5.5V
• Propagation Delay Time: 9ns at 5V
• Output Current: ±24mA

Applications

The CD74ACT273SM is suitable for a wide range of applications including:

• Buffer/Storage Registers
• Shift Registers
• Pattern Generators

Product Description

The device consists of eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The common buffered Clock (CP) and Master Reset (MR) inputs load and reset all flip-flops simultaneously. The register is fully edge-triggered. The state of each D input, one setup time before the Low-to-High clock transition, is transferred to the corresponding flip-flop’s Q output.

The CD74ACT273SM is characterized for operation from -55°C to 125°C, making it suitable for military-grade applications. It is also ideal for the buffering of data in computers, instrumentation, and other systems that require high-speed and low power consumption. Its fast propagation delay and high current drive are critical for high-speed data processing and storage.

With its robust packaging, the CD74ACT273SM is designed for surface mounting, and it fits perfectly into automated assembly lines, ensuring reliability and ease of integration into a wide variety of electronic systems.

Quality and Reliability

Texas Instruments is renowned for its commitment to quality and reliability, and the CD74ACT273SM is no exception. It undergoes rigorous testing and quality control measures to ensure it meets the high standards expected from a leading semiconductor manufacturer.
