Working Principles

The 74LVT373SJ operates as an octal transparent latch with 3-state outputs. When the latch enable (LE) input is high, the data inputs (D0-D7) are transferred to the corresponding outputs (Q0-Q7). The output enable (OE) input controls the state of the outputs. When OE is low, the outputs are active and reflect the input data. When OE is high, the outputs are in a high-impedance state, allowing other devices to drive the bus.

Detailed Application Field Plans

The 74LVT373SJ can be used in various digital systems and applications, including: - Microprocessor and microcontroller interfacing - Data storage and retrieval systems - Address decoding and bus control circuits - Communication systems - Industrial automation and control systems
