Working Principles

The 74HCT573D,653 is an octal D-type transparent latch that stores and outputs data in an 8-bit format. The latch is controlled by the Latch Enable (LE) input, which determines when the data is stored. The Output Enable (OE) input enables or disables the outputs. When the LE input is high, the latch stores the data present at the inputs. The stored data can then be read from the outputs when the OE input is also high.

Detailed Application Field Plans

The 74HCT573D,653 is commonly used in various applications, including: 1. Microprocessor-based systems 2. Data communication systems 3. Industrial control systems 4. Automotive electronics 5. Consumer electronics
