Working Principles

The PI74LPT373AS operates based on transparent latch functionality. When the output enable (OE) signal is active, the data inputs (D0-D7) are latched and transferred to the corresponding latch outputs (Q0-Q7). The latch remains transparent as long as the OE signal is active, allowing continuous data flow. When the OE signal is inactive, the latch holds the last latched data until the OE signal becomes active again.

Detailed Application Field Plans

The PI74LPT373AS finds application in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Data storage devices - Communication systems - Industrial automation equipment - Consumer electronics
