Functional Features

The 74ABT373AD,118 offers the following functional features:

• Transparent latch operation: The data inputs (D0-D7) are transferred to the outputs (Q0-Q7) when the latch enable (LE) input is high.
• Output enable control: The outputs can be enabled or disabled using the output enable (OE) input.
• Clock-controlled operation: The clock pulse (CP) input synchronizes the transfer of data from the inputs to the outputs.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Low power consumption helps in reducing overall system energy requirements. - Wide operating voltage range provides flexibility in various applications. - Schmitt-trigger action on all inputs ensures noise immunity. - Balanced propagation delays ensure reliable timing.

Disadvantages: - Limited number of flip-flops (eight in total) may restrict its use in larger systems requiring more storage elements. - Availability in only one package type (SSOP) may limit compatibility with certain circuit designs.

Working Principles

The 74ABT373AD,118 operates based on the principles of transparent latch and clock-controlled data transfer. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The clock pulse (CP) input synchronizes this transfer, ensuring accurate timing. The output enable (OE) input allows for enabling or disabling the outputs as needed.
