Working Principles

The SN74LVT16245BGQLR is designed to translate voltage levels between two different logic families. It operates by receiving data from one side and transmitting it to the other side while maintaining proper voltage levels. The direction of data flow is controlled by the Output Enable (OE) pins. When the OE pin is high, the device is in the active state, allowing data transmission. When the OE pin is low, the device is in the tri-state state, isolating the bus and preventing data interference.

Detailed Application Field Plans

The SN74LVT16245BGQLR is commonly used in various applications that require voltage level translation and bus transceiver functionality. Some specific application fields include: - Microcontroller interfacing with different logic families - Communication systems involving multiple voltage domains - Data acquisition and processing systems - Industrial automation and control systems - Automotive electronics
