  • It features three-state outputs, allowing multiple devices to share a common bus without interference.
  • The output enable (OE) pin controls the tri-state outputs, enabling or disabling their operation.
  • The latch can be clocked using the clock (CLK) input, which updates the outputs with the current input data.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Wide operating voltage range provides flexibility in various applications. - Three-state outputs enable bus sharing without interference.

Disadvantages: - Limited number of latches (8) may not be sufficient for certain applications requiring larger data storage.

Working Principles

The MM74C373N operates based on the principle of transparent latching. When the latch enable (LE) signal is high, the input data is directly transferred to the outputs. The clock (CLK) input is used to update the outputs with the current input data. The output enable (OE) pin controls the tri-state outputs, enabling or disabling their operation.
