Dual Bidirectional I2C-Bus and SMBus Voltage-Level Translator UM3212M8 MSOP8 UM3212DA DFN8 2.1×1.6 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. When EN is HIGH, the translator switch is on, and the SCL1 and SDA1 I/O are connected to the SCL2 and SDA2 I/O, respectively, allowing bidirectional data flow between...
