Working Principles

The 74LVTH543MTC is a level shifter and bus transceiver IC that enables bidirectional voltage level translation between two voltage domains. It operates by receiving data from one domain, translating it to the appropriate voltage level, and transmitting it to the other domain. The direction of data flow is controlled by the DIR input, while the LE input allows latching the data on the outputs. The OE input enables or disables the outputs.

Detailed Application Field Plans

The 74LVTH543MTC is commonly used in various digital systems where there is a need to interface between devices operating at different voltage levels. Some typical application fields include:

1. Microcontroller interfacing with peripheral devices
2. Communication interfaces between different logic families
3. Level shifting in battery-powered portable devices
