The 74HCT273ANSR is a high-performance integrated circuit designed and manufactured by Texas Instruments, a leader in semiconductor solutions. This particular device is part of the 74HCT family, which is known for its compatibility with TTL (Transistor-Transistor Logic) levels while operating at the higher speeds of CMOS technology.

Key Features

• Logic Type: Octal D-Type Flip-Flop with Clear
• Number of Pins: 20
• Package: SOIC (Small Outline Integrated Circuit)
• Operating Temperature: -40°C to +85°C, making it suitable for industrial applications
• Supply Voltage Range: 4.5V to 5.5V, which is typical for 5V logic families
• Propagation Delay Time: Fast propagation delay, ensuring high-speed operation for critical applications

Functional Description

The 74HCT273ANSR contains eight edge-triggered, D-type flip-flops with a common clear input. Each flip-flop has independent D (data) inputs and Q (output) outputs. The device provides a convenient way to interface with and control multiple data lines or to create registers, counters, and toggle functions in a system.

A low level at the clear input sets all eight of the flip-flop outputs low, regardless of the clock input or data inputs, providing a synchronous reset feature for all flip-flops. The flip-flops transition on the rising edge of the clock input signal, capturing the state of their respective D inputs.

Applications

The 74HCT273ANSR is versatile and can be used in a wide range of applications, including:

• Storage registers
• Power-on reset for digital systems
• Buffer registers for data management
• Counter and toggle functions
• Control systems
