Working Principles

The SN74AC373MDWREP operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data on the D0-D7 inputs is transferred to the corresponding Q0-Q7 outputs. The latch holds this data until a new set of inputs is provided. The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The SN74AC373MDWREP can be used in various applications, including:

1. Microprocessor-based systems
2. Data storage systems
3. Communication equipment
4. Industrial automation
5. Automotive electronics
