Working Principles

The MC74LCX373DWR2 is an octal transparent latch that stores 8 bits of data. It operates based on latch enable (LE) and output enable (OE) control signals. When the LE signal is high, the latch is transparent, allowing the data inputs (D0-D7) to propagate to the outputs (Q0-Q7). The OE signal controls the output state, enabling or disabling the outputs.

Detailed Application Field Plans

The MC74LCX373DWR2 is commonly used in various digital systems, including:

  1. Microprocessors and microcontrollers
  2. Data storage systems
  3. Communication equipment
  4. Industrial automation
  5. Automotive electronics
