Product Overview: 74HC273BQ Octal D-Type Flip-Flop

The 74HC273BQ, manufactured by NXP Semiconductors, is a high-speed Si-gate CMOS device that is part of the 74HC/HCT family. This integrated circuit is specifically designed as an octal D-type flip-flop with a clear feature. It is a versatile component used in a wide range of digital applications, from simple logic control to complex data storage and transfer systems.

Key Features

• Logic Type: D-Type Flip-Flop
• Number of Pins: 20
• Number of Elements: 8
• Supply Voltage Range: 2.0V to 6.0V
• Output Current: High-level: 5.2 mA; Low-level: 5.2 mA
• Logic Case Style: DHVQFN
• Propagation Delay: 13 ns
• Operating Temperature Range: -40°C to +125°C

Functional Description

The 74HC273BQ contains 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. The flip-flops will store the state of their individual D-inputs that meet the setup and hold time requirements on the LOW-to-HIGH clock (CP) transition. A LOW on MR clears all flip-flops, forcing all Q outputs LOW, independent of the clock.

Applications

Due to its high-speed performance and wide operating voltage range, the 74HC273BQ is suitable for a variety of applications. These include:

• Buffer/Storage Registers
• Shift Registers
• Data Storage
• Pattern Generators

Quality and Reliability

NXP's commitment to quality ensures that the 74HC273BQ meets stringent industry standards for performance and reliability. The device is available in a DHVQFN20 package, which is known for its small footprint and high thermal performance, making it ideal for space-constrained applications.

With its robust design and versatile functionality, the 74HC273BQ from NXP is an excellent choice for designers looking to implement reliable flip-flop logic in their digital systems.
