Datasheet	UM2102 Datasheet

General Description

The UM2102S allows bidirectional voltage translations between 1.5V and 5V without the use of a direction pin.

The UM2012S is not a bus buffer which provides both level translation and physically isolates the capacitance to either side of the bus when both sides are connected.

The UM2102S only isolates both sides when the VREF is connected to GND.
