The NXP 74HCT273AFW is a high-performance, octal D-type flip-flop with a clear feature, designed for use in systems that require the capture and retention of data. This integrated circuit is part of the 74HCT family, which is well known for its high-speed CMOS technology. The 74HCT273AFW is particularly suitable for applications that necessitate the synchronous control of data by a clock signal and where the ability to clear the data is essential.

Key Features

• Logic Type: Octal D-type flip-flop with clear
• Operating Voltage: 4.5V to 5.5V, making it compatible with TTL levels
• High-Speed Performance: Typical shift frequency of 100 MHz
• Output Capability: Standard outputs capable of driving up to 15 LSTTL loads
• Clear Function: Asynchronous master reset input for all flip-flops

Product Specifications

The NXP 74HCT273AFW features eight edge-triggered, D-type flip-flops with individual D inputs and Q outputs. The common clock (CP) and master reset (MR) inputs control all flip-flops. A LOW on MR clears all flip-flops, irrespective of the state of CP or the D inputs, ensuring that the output Q is LOW. This is a critical feature for system initialization and for avoiding undefined states in digital circuits.

Designed for robustness, the 74HCT273AFW can operate within a temperature range of -40°C to +125°C, making it suitable for industrial applications. The device comes in a wide-body SO20 package, ensuring adequate heat dissipation and ease of PCB layout.

Applications

The versatility of the NXP 74HCT273AFW makes it ideal for a variety of applications including:

• Memory registers
• Data storage devices
• System initialization and reset control circuits
• Interface circuitry between systems
