Introduction
The ADuM1252 provides two bidirectional open-drain channels for applications requiring bidirectional data transfer on the same line, such as I2C. To prevent latch-up, Side 1 outputs use special buffers that regulate the logic-low voltage to 0.64V, with the input logic-low threshold at least 50mV below the output logic-low voltage. Side 2 uses conventional buffers without regulation of the logic-low output voltage. The ADuM1252 supports independent 1.71V to 5.5V supplies on both Side 1 and Side 2 of the isolator. The device operates at up to 2MHz. An ultralow standby current of 21μA per side makes it ideal for battery-powered systems. The ADuM1252 provides glitch-free bus connection for hot-plug connections on Side 2 by first precharging the bus pins, then monitoring the bus state before connecting Side 1 and Side 2 to determine whether the bus is idle or an I2C stop condition has been detected. The ADuM1252 is available in 8-lead narrow-body and wide-body SOIC packages and an 8-lead MSOP package. The device is rated for an operating ambient temperature range of −40°C to +125°C.
Features
- Low VOL(MAX) for improved I2C device compatibility
