UM2102 Datasheet (Union Semiconductor) - 2-Bit Bidirectional Voltage Level Translator

UM2102, 2-Bit Bidirectional Voltage Level Translator

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 isola
