Hello

I think you should make an interfacing board based on the TXS0108 from Texas instruments.

It is a 8-Bit Bidirectional Voltage-Level Translator For Open-Drain And Push-Pull Application, see:
http://www.ti.com/product/txs0108e

Volume price: 1.5-2.0 $

I propose a breakout that contains the above device and could it could be supplemented with the following:
A voltage regulator for driving the "low" side of the device, perhaps even with dip-switches to select voltage ie. 1.8v; 3.3v
A dip-switch to enable the device permanently or let it be controlled by an external signal

BR, Zerodamage

Please note that I was not asking for a way to solve the level-shifting problem, i was making a product suggestion

While I'm aware of that existing product I think my proposal covers a wider range of functionality and usefulness, for example it provides:
- driving capabilities in both directions (buffering)
- more channels
- output enable/disable (3-stated)
- ESD protection

I have also found need for such a device, and the existing level shifter board doesn't quite fit the bill. I'd buy it if you made it.

We have something similar based on the TXS0401 chip, including regulator down to 3.3V.
