Overview
EVALUATION KIT AVAILABLE MAX14591 High-Speed, Open-Drain Capable Logic-Level Translator General Description The MAX14591 is a dual-channel, bidirectional logiclevel translator with the level shifting necessary to allow data transfer in a multivoltage system.
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 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 -40NC to +85NC temperature range, and is available in 8-bump WLP and 8-pin TDFN packages.
