Product Overview: SN74AHCT273NSR by Texas Instruments

The SN74AHCT273NSR is a high-performance, octal D-type flip-flop with a clear function, designed and manufactured by Texas Instruments. This integrated circuit is part of the 'AHCT' family, which is known for its advanced high-speed CMOS technology. It is specifically designed to operate with a 4.5V to 5.5V power supply, making it suitable for interfacing with 5V systems.

The SN74AHCT273NSR features eight D-type flip-flops with direct clear inputs. Each flip-flop is edge-triggered and will capture the state of their individual D-inputs on the rising edge of the clock signal. The clear function is synchronous, ensuring that all outputs can be simultaneously cleared by a high level on the clear input, providing users with a reliable and quick way to reset their system.

This device is available in a compact 20-SOIC (0.209", 5.30mm Width) package, which is designed for space-efficient applications and ensures a small footprint on printed circuit boards. It is commonly used in a wide range of digital applications, including data storage, communication systems, and complex microprocessors where high-speed, low-power operation is required.

The SN74AHCT273NSR is characterized for operation from -40°C to 85°C, making it robust and reliable for industrial applications. Its balanced propagation delays and transition times further enhance its performance in fast-paced environments where timing is critical.

Key features of the SN74AHCT273NSR include:

• Eight edge-triggered D-type flip-flops with clear
• Wide operating voltage range of 4.5V to 5.5V
• Outputs can drive up to 15 LSTTL loads
• Low power consumption
• ±8-mA output drive at 5V
• Low input current of 1 μA maximum
• Direct clear for synchronous reset
• Industrial temperature range of -40°C to 85°C

With its robust design and versatile features, the SN74AHCT273NSR from Texas Instruments is an excellent choice for designers looking to implement reliable data storage or state machine functions in their electronic projects.
