Working Principles

The SN74AS4374BDWRG4 is an octal D-type transparent latch with 3-state outputs. It operates based on the clock pulse (CP) input and the data inputs (D0-D7). When the CP input is high, the latch is transparent, meaning the data inputs are transferred to the outputs. When the CP input is low, the latch holds the last transferred data. The Output Enable (OE) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.

Detailed Application Field Plans

The SN74AS4374BDWRG4 can be used in various digital logic applications, including but not limited to: - Data storage and transfer systems - Address decoding circuits - Bus interface units - Memory modules - Microprocessor-based systems
