• Octal D-Type Flip-Flop: The IC consists of eight individual D-type flip-flops, allowing for the storage and transfer of data.
• High-Speed Operation: The CMOS logic design enables high-speed operation, making it suitable for applications that require quick data processing.
• Clear Function: The CLR pin allows for the clearing of all flip-flop outputs to a low state, providing a convenient way to reset the circuit.
• Clock Pulse Input: The CP pin serves as the clock pulse input, controlling the timing of data storage and transfer.

Advantages and Disadvantages

Advantages of the MM74HC273MTC include:

• High-speed operation
• Compact TSSOP-20 package

• Relatively low output current capacity

Working Principles

The MM74HC273MTC operates based on the principles of D-type flip-flops. When a clock pulse is applied to the CP pin, the data present at the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The stored data remains unchanged until the next clock pulse is received. The CLR pin can be used to clear all outputs simultaneously.
