Functional Features

• Octal transparent latch: The 74ACTQ373PC can store and transfer data in eight separate latches, allowing for efficient handling of multiple bits of information.
• 3-state outputs: The outputs of the latch can be put into a high-impedance state, enabling multiple devices to share the same bus without interference.
• High-speed operation: With a maximum propagation delay time of 6ns, the 74ACTQ373PC is suitable for applications that require fast data transfer.

Advantages and Disadvantages

Advantages: - Efficient data storage and transfer capabilities - Compatibility with other digital systems - High-speed operation

Disadvantages: - Limited number of latches (8) - Requires external clock pulse for operation

Working Principles

The 74ACTQ373PC operates based on the principles of digital logic. When the clock pulse (CP) input is triggered, the latch captures the data present at the D0-D7 inputs and stores it internally. The stored data can then be accessed from the Q0-Q7 outputs. The Output Enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74ACTQ373PC finds application in various digital systems where data storage and transfer are required. Some specific application fields include:

1. Microprocessors and microcontrollers
2. Memory systems (RAM, ROM)
3. Data communication devices
4. Industrial control systems
5. Automotive electronics

Detailed and Complete Alternative Models

• 74ACTQ373SC: Surface Mount Package (SOIC)
• 74ACTQ373MTCX: Tape and Reel Packaging (TSSOP)
