Working Principles

The 74LVTH2245D,112 is a bidirectional level shifter and bus transceiver IC. It operates by translating signals between two voltage domains, allowing devices operating at different voltage levels to communicate with each other. The direction of data flow is controlled by the DIR pin. When the DIR pin is set to a logic high or low, the corresponding channel allows data transmission from A to B or from B to A, respectively. The OE pin enables or disables the outputs, providing control over the tri-state functionality.

Detailed Application Field Plans

• Interfacing between microcontrollers and peripheral devices operating at different voltage levels
• Communication between different logic families (e.g., TTL and CMOS)
• Level shifting in communication protocols such as I2C, SPI, and UART
• Bus transceiver for address and data buses in embedded systems
• Voltage level translation in mixed-voltage systems
