I knew that ST202 is compatible for ST3232. So I changed only ST202 into ST3232 without any circuit changing.But ST3232 doesn't work.What is different between ST3232 and ST202, other than power supply voltage?I found the difference in typical appli...

Hello. I'm interesting about ST202EBTR. If I use it in 3.3V, what difference is it compered in 5V.

Thank you for your reply.I use ST202 in 5V and use ST3232 in 3.3V.In ST3232, capacitors (C1-C4) are 0.1uF.I use non-polar chip capacitors.In datasheet, direction of V- capacitor is different from others.Should I use polarized capacitors?

Dear Peter,Thank you for your reply.In datasheet, "Absolute maximum ratings" writes "Supply voltage" range is "-0.3 to 6".So I thought ST202EBTR moved at 3.3V.But it isn't correct, is it? (At 3.3V, it doesn't move.)I'm happy that you gave me infor...
