Hello,
We need to convert 3.3V cmos logic to logic for a gate driver where -2.5V is high and -5V is low. Do we have any voltage translators or ICs that can help accomplish this?
Thanks!

Hello,
All of our voltage translators have a shared ground, so we don't have anything that will shift ground from 0V down to -5V at the output -- they only really change the positive voltage (for example, 3.3V to 5V). The most common way I know of to achieve this is by using the circuit described here:

If you're looking to drive a GAN fet (or similar device), you might try posting under the part # LMG1020, which would notify the GAN drivers team -- they might have a solution.
