Working Principles

The CD74ACT373EG4 is an octal transparent latch with 3-state outputs. It stores and retrieves 8-bit data using a latch enable signal (LE). When the LE signal is high, the input data is latched and appears at the outputs (Q0-Q7). The output enable signal (OE) controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

1. Data storage and retrieval systems: The CD74ACT373EG4 can be used in various applications that require temporary storage of data, such as microprocessors, memory modules, and communication devices.
2. Address decoding: It can be employed in address decoding circuits to select specific memory locations or peripheral devices.
3. Bus interfacing: The IC facilitates bidirectional data transfer between different components of a system, enabling efficient communication.
