Functional Features

The 74AC373SC offers the following functional features:

• Octal transparent latch with three-state outputs
• High-speed operation allows for efficient data transfer
• Output enable (OE) pin controls the output state, enabling or disabling the outputs
• Clock pulse (CP) pin triggers the latch to store the input data
• Three-state outputs provide flexibility in connecting multiple devices

Advantages and Disadvantages

Advantages

• High-speed operation enables fast data transfer
• Low power consumption contributes to energy efficiency
• Wide operating voltage range allows for compatibility with various systems
• Compact SOIC package facilitates integration into electronic circuits

Disadvantages
