Description: I2C Isolator

Features

* conventional buffers that do not regulate logic-low output voltage. The ADuM1253 features independent 1.71V to 5.5V supplies on both side 1 and side 2 of the isolator. The device operates up to 2MHz. The ultra-low standby current of 21µA per side is ideal for battery-operated systems. The ADuM1253 p

Applications

* such as I2C, that require data to be transmitted in both directions on the same line but have a unidirectional clock. To prevent latch-up action, side 1 outputs comprise special buffers that regulate the logic-low voltage at 0.64V, and the input logic-low threshold is at least 50mV lower than the o
