Functional Features

• Octal transparent latch with 3-state outputs
• High-speed operation for digital logic applications
• Output enable and latch enable control signals for flexible data storage and output control
• 3-state outputs allow multiple devices to share a common bus without interference

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient digital logic processing - Flexible data storage and output control through control signals - 3-state outputs facilitate bus sharing among multiple devices

Disadvantages: - Limited supply voltage range of 2.0V to 6.0V - Maximum dynamic supply current of 25mA may require additional power management considerations

Working Principles

The MC74HC573ADTG operates as an octal transparent latch with 3-state outputs. It stores data from the input pins when the latch enable (LE) signal is active. The stored data can be outputted to the corresponding output pins when the output enable (OE) signal is active. The 3-state outputs allow the device to disconnect from the shared bus, preventing interference when not in use.
