Functional Features

• Transparent latch operation: The 74LVQ373MTR allows data to pass through when the latch enable (LE) pin is high.
• 3-state outputs: The outputs can be in a high, low, or high impedance state, controlled by the output enable (OE) pin.
• Octal design: With eight individual latches, this IC provides flexibility in storing and controlling multiple data inputs.

Advantages and Disadvantages

Advantages

• High-speed operation: The 74LVQ373MTR operates at a maximum frequency of 200MHz, making it suitable for high-performance applications.
• Low power consumption: This IC is designed to operate with a low supply voltage range, resulting in reduced power consumption.
• Compact package: The surface mount package allows for easy integration into electronic systems.

Disadvantages

• Limited output current: The 74LVQ373MTR has a limited output current capacity, which may restrict its use in certain applications requiring higher current levels.
• Sensitivity to voltage fluctuations: As with most integrated circuits, this IC may be sensitive to voltage fluctuations, requiring proper voltage regulation.

Working Principles

The 74LVQ373MTR operates based on the principles of latch-based storage and control. When the latch enable (LE) pin is high, the data inputs are transparently passed through to the outputs. The output enable (OE) pin controls the state of the outputs, allowing them to be either active or in a high impedance state.
