• Output enable (OE1) input for 3-state control
• High-speed operation for efficient data transfer
• Low-voltage operation for power efficiency

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with various systems - High-speed operation ensures efficient data transfer - 3-state outputs enable bus-oriented applications

Disadvantages: - Limited output drive capability of ±24mA - Operating temperature range may not be suitable for extreme environments

Working Principles

The 74LVQ373SJ is an octal transparent latch that stores data when the latch enable (LE) input is high. The stored data can be transferred to the outputs when the clock (CLK) input transitions from low to high. The output enable (OE1) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The 74LVQ373SJ IC finds applications in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Data storage systems - Communication devices - Industrial automation equipment - Automotive electronics
