Functional Features

• Transparent Latching: The 74ALVC373PW,118 allows data to be latched transparently when the clock signal is active.
• 3-State Outputs: The IC provides 3-state outputs, allowing multiple devices to share a common bus without interference.
• High-Speed Operation: With a maximum propagation delay of 2.5ns, the IC enables fast data transfer in electronic systems.
• Low Power Consumption: The 74ALVC373PW,118 is designed to operate at low supply voltages, resulting in reduced power consumption.

Advantages and Disadvantages

Advantages: - High-speed operation facilitates efficient data transfer. - Low power consumption helps conserve energy. - 3-state outputs enable bus sharing among multiple devices. - Transparent latching simplifies data storage and transfer.

Disadvantages: - Limited number of latches (8) may not suffice for complex applications requiring more storage elements. - TSSOP package may be challenging to solder manually due to its small size.

Working Principles

The 74ALVC373PW,118 operates based on the principle of transparent latching. When the clock signal (CLK) is active, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The latch remains transparent as long as the clock signal is active, allowing real-time data transfer. When the clock signal becomes inactive, the latched data remains stored until the next clock cycle.

Detailed Application Field Plans

The 74ALVC373PW,118 finds applications in various electronic systems that require data storage and transfer. Some potential application fields include:

1. Microcontrollers: The IC can be used to store and transfer data between microcontrollers and peripheral devices.
2. Communication Systems: It enables efficient data transfer between different communication modules or protocols.
3. Memory Interfaces: The IC can serve as a buffer for memory interfaces, ensuring reliable data transfer.
4. Industrial Automation: It can be utilized in control systems to store and transfer data between sensors, actuators, and controllers.
