Functional Features

• Octal transparent latch with 3-state outputs
• High-speed operation, suitable for applications requiring fast data transfer
• CMOS compatible inputs, allowing easy interfacing with other logic devices
• Latch enable and output enable pins for control over the latching and output functions
• 3-state outputs provide flexibility in bus-oriented systems

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer - CMOS compatibility ensures easy integration with other logic devices - 3-state outputs provide flexibility in bus-oriented systems

Disadvantages: - Limited voltage range of 2.0V to 6.0V may not be suitable for all applications - DIP package may not be ideal for space-constrained designs

Working Principles

The MC74HCT573ANG is an octal transparent latch that stores data when the latch enable (LE) input is high. When LE is low, the latch remains transparent, allowing the data inputs to pass through to the outputs. The output enable (OE) input controls the tri-state outputs, enabling or disabling their functionality.
