Working Principles

The 74LVQ373QSC is an octal transparent latch with 3-state outputs. It operates by latching the data inputs (D0-D7) when the latch enable (LE) input is activated. The latched data is then available at the corresponding outputs (Q0-Q7). The output enable (OE) input controls whether the outputs are enabled or disabled. When disabled, the outputs enter a high-impedance state, allowing other devices to drive the bus lines.

Detailed Application Field Plans

The 74LVQ373QSC is commonly used in various applications, including: - Data storage and transfer systems - Address decoding circuits - Bus interface units - Memory modules - Microprocessor-based systems - Communication equipment
