MAX14595 High-Speed, Open-Drain Capable Logic-Level Translator

The MAX14595 is a dual-channel, bidirectional logic-level translator designed specifically for low power consumption making it suitable for portable and battery-powered equipment. Externally applied voltages, VCC and VL, set the logic levels on either side of the device. A logic signal present on the VL side of the device appears as the same logic signal on the VCC side of the device, and vice-versa.

The device is optimized for the I2C bus as well as the management data input/output (MDIO) bus where often high-speed, open-drain operation is required. When TS-bar is high, the device allows the pullup to be connected to the I/O port that has the power. This allows continuous I2C operation on the powered side without any disruption while the level translation function is off.

The part is specified over the extended -40°C to +85°C temperature range, and is available in 8-bump WLP and 8-pin TDFN packages.
