Overview

The ADuM1253 offers two open- drain channels, one unidirectional and one bidirectional for 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 output logic- low voltage. Side 2 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 provides a disturbance- free bus connection for hot- plug connections on side 2 by first precharging the bus pins and then monitoring the bus state for either an idle bus or detection of a I2C stop condition before connecting side 1 and side 2. The ADuM1253 is available in both an 8- pin narrow- and wide- body SOIC package, and in an 8- pin MSOP package. The device is rated for operation at ambient temperatures of - 40°C to +125°C
