EVALUATION KIT AVAILABLE MAX14595 Low-Power Dual-Channel Logic-Level Translator S Meets Industry Standards General Description 2 I C Requirements for Standard, Fast, and High* Speeds The MAX14595 is a dual-channel, bidirectional logic- MDIO Open Drain Above 4MHz* level translator designed specifically for low power S Allows Greater Design Flexibility consumption making it suitable for portable and battery- Down to 0.9V Operation on V Side L powered equipment. Externally applied voltages, V CC Supports Above 8MHz Push-Pull Operation and V , set the logic levels on either side of the device. A L logic signal present on the V side of the device appears S Ultra-Low Power Consumption L as the same logic signal on the V side of the device, 7A V Supply Current CC CC 3A V Supply Current and vice-versa. L 2 S Provides High Level of Integration The device is optimized for the I C bus as well as the Pullup Resistor Enabled with One Side Power management data input/output (MDIO) bus where often Supply when TS Is High high-speed, open-drain operation is required. When TS I (max) Internal Pullup 12k is high, the device allows the pullup to be connected to : 17I (max) Low Transmission Gate R ON the I/O port that has the power. This allows continuous 2 I C operation on the powered side without any disruption S Saves Space while the level translation function is off. 8-Bump, 0.4mm Pitch, 0.8mm x 1.6mm WLP Package The part is specified over the extended -40NC to +85NC 8-Pin, 2mm x 2mm TDFN Package temperature range, and is available in 8-bump WLP and 8-pin TDFN packages. Applications *Requires external pullups.
