Working Principles

CD74AC573E operates as an octal transparent latch, meaning that the input data is transferred to the outputs when the latch enable (LE) signal is high. The latch remains transparent as long as the output enable (OE) signal is also high. When the LE signal goes low, the data at the inputs is latched and held at the outputs until a new data transfer occurs.

Detailed Application Field Plans

CD74AC573E finds extensive use in various digital electronic systems, including but not limited to: - Microprocessors and microcontrollers - Data storage devices - Communication systems - Industrial automation - Automotive electronics
