EVALUATION KIT AVAILABLE MAX14591 High-Speed, Open-Drain Capable Logic-Level Translator General Description Benefits and Features S Meets Industry Standards The MAX14591 is a dual-channel, bidirectional logic- 2 level translator with the level shifting necessary to allow I C Requirements for Standard, Fast, and data transfer in a multivoltage system. Externally applied High* Speeds voltages, V and V , set the logic levels on either side CC L MDIO Open Drain Above 4MHz* of the device. A logic signal present on the V side of the L S Allows Greater Design Flexibility device appears as the same logic signal on the V side CC Down to 0.9V Operation on V Side L of the device, and vice-versa. Supports Above 8MHz Push-Pull Operation 2 The device is optimized for the I C bus as well as the S Offers Low Power Consumption management data input/output (MDIO) bus where often 23A (typ) V Supply Current CC high-speed, open-drain operation is required. When TS 0.5A (typ) V Supply Current is high, the device allows the pullup to be connected to L the I/O port that has the power. This allows continuous S Provides High Level of Integration 2 I C operation on the powered side without any disruption Pullup Resistor Enabled with One Side while the level translation function is off. Power Supply when TS Is High 12kI (max) Internal Pullup The part is specified over the extended -40NC to +85NC temperature range, and is available in 8-bump WLP and Low Transmission Gate R : 17I (max) ON 8-pin TDFN packages.
