General Description

The UM3212 is a dual bidirectional I2C-bus and SMBus voltage-level translator with an enable (EN) input, and is operational from 1.0V to 3.6V (Vref(1)) and 1.8V to 5.5V(Vbias(ref)(2)).

The UM3212 allows bidirectional voltage translations between 1.0V and 5V without the use of a direction pin.

The low ON-state resistance (Ron) of the switch allows connections to be made with minimal propagation delay.

Key Features

z 2-Bit Bidirectional Translator for SDA z Open-Drain I2C-Bus I/O Ports (SCL1, and SCL Lines in Mixed-Mode I2C-Bus SDA1, SCL2 and SDA2).
