Working Principles

The 74ACT373PC operates based on the principle of transparent latching. When the latch enable (LE) signal is active, the inputs (D0-D7) are transferred to the outputs (Q0-Q7). The output enable (OE) signal controls whether the outputs are enabled or disabled. When the OE signal is active, the outputs are in a high-impedance state, allowing other components to drive the bus.

Detailed Application Field Plans

The 74ACT373PC finds applications in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Memory systems - Data storage devices - Communication systems - Industrial automation
