• Requires external control signals for proper operation, which may increase system complexity.

Working Principles

The CD74ACT373M96E4 operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The output enable (OE) input controls whether the outputs are active or in a high-impedance state.

The latch operates on positive-edge clocking, meaning that the data inputs are captured and stored on the rising edge of the latch enable signal. This allows for synchronized data transfer within a digital system.

The CD74ACT373M96E4 can be used in various applications where data storage and transfer are required. Some potential application fields include:

1. Microcontrollers and microprocessors
2. Data communication systems
3. Memory modules
4. Industrial automation
