Working Principles

The 74AHC373D,118 is an octal transparent latch that stores data when the latch enable (LE) input is high. The stored data can be read from the outputs when the output enable (OE) input is low. The latch operates on a positive-edge clock signal (CP). When CP transitions from low to high, the data inputs are transferred to the outputs if LE is high. Otherwise, the outputs remain in their previous state.

Detailed Application Field Plans

The 74AHC373D,118 is commonly used in various digital systems, including but not limited to: - Microprocessor-based systems - Data storage systems - Communication equipment - Industrial control systems - Automotive electronics
