  • High-speed operation
  • Non-inverting outputs
  • Latch enable and output enable control signals
  • Direct interface with TTL levels
  • Low power consumption
  • ESD protection on all inputs and outputs

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data storage and retrieval - 3-state outputs enable easy data transfer to other devices - Low power consumption helps in energy-efficient designs - ESD protection ensures reliability in harsh environments

Disadvantages: - Limited number of input and output pins restricts the number of connections that can be made - Not suitable for applications requiring a large number of latches

Working Principles

The MM74HC373SJ operates as an octal transparent latch. When the latch enable (LE) signal is high, the data inputs (D0-D7) are transferred to the outputs (Q0-Q7). The output enable (OE) signal controls whether the outputs are active or in a high-impedance state.
