Functional Features

SN74LVC573ANSRE4 offers the following functional features:

• Octal transparent latch: Allows data to be stored and outputted on the rising edge of the latch enable signal.
• 3-state outputs: Enables bus-oriented applications by providing high impedance state when the output enable signal is low.
• Schmitt-trigger inputs: Provides noise immunity by ensuring a clean transition between logic levels.

Advantages and Disadvantages

Advantages

• High-speed operation: Suitable for applications requiring fast data transfer.
• Low power consumption: Helps in reducing overall power consumption of the system.
• Noise immunity: Schmitt-trigger inputs ensure reliable operation in noisy environments.

Disadvantages

• Limited output current: The maximum output current is ±32mA, which may not be sufficient for certain applications.
• Temperature limitations: The operating temperature range of -40°C to +85°C may restrict usage in extreme temperature conditions.

Working Principles

SN74LVC573ANSRE4 operates based on the principles of digital storage and output control. When the latch enable (LE) signal is high, the data inputs (D0-D7) are latched and stored. On the rising edge of the LE signal, the stored data is transferred to the corresponding outputs (Q0-Q7). The output enable (OE) signal controls the state of the outputs, allowing them to be either active or in a high impedance state.
