Working Principles

The ADM241LJRSZ is a level translator IC that facilitates bidirectional voltage level translation between two different voltage domains. It uses a combination of MOSFETs and control circuitry to achieve the desired translation. The DIR pin controls the direction of translation, while the OE pin enables or disables the output. The device automatically senses the direction based on the voltage levels applied to the input pins.

Detailed Application Field Plans

• Interfacing between microcontrollers operating at different voltage levels
• Communication between devices using different logic families (e.g., TTL and CMOS)
• Level shifting in battery-powered portable devices
• Industrial automation systems requiring voltage level translation
• IoT (Internet of Things) applications involving multiple voltage domains
