The CD74HC273M is a high-speed CMOS logic octal D-type flip-flop with a clear feature, manufactured by Texas Instruments. Designed to operate at a wide voltage range from 2V to 6V, this device is part of the 74HC family, ensuring compatibility with all CMOS and TTL logic levels. It is particularly suitable for implementing buffer registers, I/O ports, bidirectional bus drivers, and working registers.

Key Features

• Logic Type: Octal D-Type Flip-Flop with Clear
• Operating Voltage Range: 2V to 6V
• High-Speed Performance: Typical t_PD of 13ns at 5V
• Low Power Consumption: 80 µA maximum ICC at 5V
• Output Drive Capability: 15 LSTTL loads
• Package: SOIC-20

Functional Description

The CD74HC273M contains eight D-type flip-flops with a common clear input. Each flip-flop is edge-triggered and transfers data from its D-input to the Q-output on the rising edge of the clock pulse. A low level at the clear input sets all outputs to a low level, regardless of the clock or data inputs. The high-speed performance of this device significantly reduces propagation delay times, making it an excellent choice for high-frequency applications.

Applications

This versatile component is widely used in a variety of digital applications. Some common use cases include:

• Buffer Registers
• I/O Ports
• Bidirectional Bus Drivers
• Working Registers
• Control Registers
