  • 3-state outputs allow easy bus interfacing
  • High-speed operation suitable for time-critical applications
  • Latch enable and output enable pins provide control over data storage and transfer

Advantages and Disadvantages

Advantages: - High-speed operation enables efficient data transfer - 3-state outputs facilitate easy interfacing with other components - Individual data inputs and outputs offer flexibility in system design

Disadvantages: - Limited number of latches (8) may not be sufficient for complex systems requiring more storage capacity - Requires external control signals for proper operation

Working Principles

The DM74ALS373SJX is a transparent latch, which means that the input data is directly transferred to the outputs when the latch enable (LE) signal is active. The output enable (OE) signal controls whether the outputs are enabled or disabled. When the OE signal is active, the outputs are in a high-impedance state, allowing other devices to drive the bus.
