I am building a project using a type of RS232 level translator that runs on just +5 Vdc.
The actual part is a Sipex/Exar SP207HCP, but I guess my question would apply to any similar IC that use charge pumps to build up the RS232 level voltages.
My Question is, must I used polarized capacitors as the charge pump capacitors ?
I have non-polarized caps that would fit much better and would prefer to use them.
I'm only going to running at 112K Baud and below - though likely no greater then 56k.
