UM3212 Datasheet (Union Semiconductor) - Dual bidirectional I2C-bus and SMBus voltage-level translator

UM3212, Dual bidirectional I2C-bus and SMBus voltage-level translator

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.
