Working Principles

The SN74AS533ADWRE4 is an octal transparent latch, which means it can store and retain data based on the input signals applied to its data inputs (D0-D7). The latch is enabled by the Latch Enable (LE) signal, allowing the data inputs to pass through to the outputs (Q0-Q7). The Output Enable (OE) signal controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AS533ADWRE4 can be used in various digital systems where data storage and retrieval are required. Some potential application fields include:

  1. Microprocessors and microcontrollers
  2. Data communication systems
  3. Memory modules
  4. Industrial automation
  5. Automotive electronics
