Designing Robust Isolated RS-232 Data Interfaces for Harsh ...

ESD Protection. Because the RS-232 cable is physically connected and disconnected by a user, ESD (electrostatic discharge) protection of the RS-232 transmit (Tx) and receive (Rx) pins (TxD1, TxD2, RxD1, RxD2) is very important, to ensure a robust and reliable interface. The ADM3252E is specified with ESD protection to IEC 1000-4-2 (801.2) on RINx and TOUTx pins as follows:

RS-485, RS-422 & RS-232 Renesas Electronics
