• Outputs can be enabled or disabled using the output enable (OE) signal
• Schmitt trigger inputs provide noise immunity and improved signal integrity
• Balanced propagation delays ensure synchronized data transfer

Advantages and Disadvantages

Advantages: - High-speed operation due to CMOS technology - Low power consumption - Schmitt trigger inputs for noise immunity - Versatile latch with 3-state outputs

Disadvantages: - Limited output drive capability - Requires external control signals for proper operation

Working Principles

The MM74HCT373WM operates as an octal transparent latch, meaning that the data inputs are directly transferred to the outputs when the latch enable (LE) signal is high. The outputs can be enabled or disabled using the output enable (OE) signal. The Schmitt trigger inputs ensure reliable data transfer by providing noise immunity.
