Working Principles

The 74LVQ373SC operates as an octal transparent latch, meaning it can store and output data in an 8-bit format. The latch is controlled by the latch enable (LE) pin, which determines when data is stored or retrieved. The output enable (OE) pin controls whether the stored data is outputted onto the bus or held in a high-impedance state.

Detailed Application Field Plans

The 74LVQ373SC is commonly used in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Memory modules - Communication devices - Industrial automation systems
