Working Principles

The SN74F2373DWE4 is an octal transparent latch that stores and outputs digital data. It operates based on the D-type latch principle, where the input data is latched and stored when the latch enable (LE) signal is active. The output enable (OE) signal controls whether the stored data is presented at the outputs (Q0-Q7). When OE is low, the outputs are enabled and reflect the stored data. Conversely, when OE is high, the outputs are disabled and enter a high-impedance state.

Detailed Application Field Plans

The SN74F2373DWE4 can be used in various applications that require temporary storage and retrieval of digital data. Some potential application fields include:

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