Working Principles

The 74AHC373PW,112 is an octal transparent latch that stores data on the rising edge of the clock signal. The latch has 8 data inputs (D0-D7) and 8 corresponding outputs (Q1-Q8). When the clock input (CP) transitions from low to high, the data present at the inputs is latched and appears at the outputs. The latch also features an output enable (OE) pin, which, when active, puts all the outputs in a high-impedance state.

Detailed Application Field Plans

The 74AHC373PW,112 is commonly used in various digital systems and applications, including:

  1. Microprocessor-based systems
  2. Data storage devices
  3. Communication equipment
  4. Industrial control systems
  5. Automotive electronics
  6. Consumer electronics
