Product Overview: CD74HCT273 from Texas Instruments

The CD74HCT273 is a high-speed CMOS logic octal positive-edge-triggered D-type flip-flop with a clear function, manufactured by the renowned semiconductor company, Texas Instruments. This integrated circuit is designed to be a part of the HCT family, which means it is compatible with standard TTL logic levels while offering the speed and power benefits of CMOS technology.

The device features eight D-type flip-flops with direct clear inputs. Each flip-flop is edge-triggered, which means that the state of the flip-flop is controlled by the data input (D) and the transition of the clock input (CLK) from low to high. When the CLK input goes high, the data on the D inputs are captured and held on the Q outputs until the next rising edge of the CLK input.

The CD74HCT273 is characterized for operation from -55°C to 125°C, ensuring reliability across a broad range of temperature conditions, making it suitable for various industrial and commercial applications. It is typically used in situations requiring data storage, data transferring, or in systems where the synchronization of data is critical.

Key Features:

• Eight D-type flip-flops with single-rail outputs
• Positive-edge trigger for all flip-flops
• Direct clear for all flip-flops
• Wide operating voltage range of 4.5V to 5.5V
• High noise immunity characteristic of CMOS devices
• Low power consumption
• Standard outputs capable of driving up to 10 LSTTL loads
• Balance propagation delays and transition times

The CD74HCT273 is offered in a variety of packages, including the space-saving surface-mount packages and the traditional dual-in-line package. This makes the device flexible for PCB design and suitable for both automated and manual assembly processes.

In conclusion, the CD74HCT273 from Texas Instruments is a versatile and reliable component for designers looking to implement flip-flops in their digital systems. Its compatibility with older TTL logic levels, combined with the advantages of CMOS technology, make it an excellent choice for a wide range of electronic applications.
