Hi, i'm looking for an RS232 transceiver with these features
- True Rs232
- 3.3V as Vcc
- ESD protection
- Lowest additional components Any suggestion? I've found ADM3202: this doesn't meets all requirements (so i'm looking for something better), but reading datasheet i have a question: is true rs232 or not? If maximum voltage (with charge pump) is +-6.6V, how it can accept +-12V as input?
