A transistor solution will allow for a wide range of level shifts and need be no more than a transistor and perhaps a resistor. That's got to be easier than wiring up an IC surely?I forgot to mention - i do not want to build a circuit, but use something that is already available. Use an IC which can do it for me, or a module i can buy easily or replace easily
thanks

One of these chips might not fulfill the requirement to higher output current though.This type of circuits is usually known as voltage level shifter and is used between 3.3V and 5V logic devices. You may do a search on eBay or Sparkfun to see if such product is available using keyword "voltage level shifter".
A cmos logic chip 'HCF40109BE' is also a logic shifter capable of 0-3V to 0-18V. It has separate Vcc and Vdd. You can download the datasheet of this chip from the net easily.

Quite true. But the OP never specify how much current he wanted to source ot sink. A transistor can either sink or source current but not both. Unless it is connected in a totem-pole way.OP said:Also increase the source and sink current.
source or sink?I see a need of 10mA normally. In some case i also see a maximum of 70mA.
