Working Principles

The TC74LCX373FK(EL,K) operates as an octal transparent latch with 3-state outputs. When the output enable (OE) pin is high, the latch is transparent, allowing the input data to pass through to the output pins. When the OE pin is low, the latch holds the last input data and the output pins enter a high-impedance state.

Detailed Application Field Plans

The TC74LCX373FK(EL,K) can be used in various digital logic applications, including but not limited to: - Microprocessor-based systems - Data storage and retrieval systems - Communication systems - Industrial control systems - Automotive electronics
