STMicroelectronics 74ACT273 Octal D-Type Flip-Flop

The 74ACT273 from STMicroelectronics is a high-speed CMOS octal D-type flip-flop with a clear feature designed to be employed in very high-speed applications. This integrated circuit is part of the 74ACT family, which is known for its high-speed performance while maintaining the CMOS low power consumption.

Key Features

• Logic Type: Octal D-Type Flip-Flop with Clear
• Operating Voltage Range: 4.5V to 5.5V
• High-Speed Performance: Typically 6ns at 5V
• Output Drive Capability: 24mA at 5V
• Bus-Friendly Outputs: New outputs can drive wired-OR or bus lines directly

Product Description

The 74ACT273 is an advanced high-speed CMOS device fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It consists of eight edge-triggered flip-flops with individual D-type inputs and Q outputs. The clear input has a dedicated function to reset all flip-flops, bringing all outputs to a low level when it is held at a high state.

Each flip-flop is designed to capture the value on the D-input at the rising edge of the clock input. The device also features a buffered clock and clear inputs to reduce the possibility of unintended state changes. The 74ACT273 is suitable for register buffer applications, where it can store eight bits of data and maintain stability until they are needed.

Applications

This versatile component is suitable for a wide range of applications including:

• Buffer storage
• Register storage
• Counters and dividers
• Relay and solenoid drivers

With its fast switching speed and high data throughput, the 74ACT273 is an excellent choice for high-performance systems that require reliable and efficient data storage and transfer.
