The MAX20326 is a dual-channel, precision, open-drain, communication-line accelerator. It provides the acceleration from a low-to-high transition necessary to allow faster data transfer in a highly capacitive, multidrop node system. The MAX20326 is optimized for the I2C bus, as well as 1-Wire® bus, where a high-speed, open-drain operation is often required with a highly capacitive load. This device is available in a 4-pin 0.5mm pitch 1.25mm x 1.25mm flip-chip QFN package and operates over the -40°C to +85°C extended temperature range. * Reliable Communication * Wide Operating Input Voltage: +1.4V to +5.5V * Precision Accelerator Trigger Threshold: 0.5V ±50mV * Fast Charge up to 1000pF Load * Low EMI: Controlled Acceleration Slope * Space Saving * 4-Pin 0.5mm Pitch 1.25mm x 1.25mm Flip-Chip QFN * Integrated Precision Pullup
