The MAX14591 is a dual-channel, bidirectional logic-level translator with the level shifting necessary to allow data transfer in a multivoltage system. It is optimized for the I2C bus and MDIO bus, providing high-speed, open-drain operation.
The MAX14591 logic‑level translator provides bidirectional voltage translation for I²C and MDIO buses, supporting operation from 0.9 V up to 5.5 V. It features low typical supply current (23 µA) and can operate at data rates above 4 MHz in open‑drain mode and above 8 MHz in push‑pull mode.
The device is offered in 8‑pin TDFN and 8‑pin WLP packages, rated for –40 °C to +85 °C operation. Electrical characteristics include internal pull‑up resistors (12 kΩ max) and a maximum continuous current of 100 mA on VCC pins. Ordering information and package outlines are provided at the end of the sheet.
