SIT3232E is a 3. 0V to 5. 5V power-supply, dual-channel, high ESD-protected, low-power RS-232 transceiver that fully meets the requirements of the TIA/EIA-232 standard. SIT3232E includes two drives and two receivers, with enhanced ESD protection function, reaching the protection capacity of HBM above 15kV and 8kV IEC-4100-4-2 contact discharge. When powered, the charge pump only needs four 0. 1μF external capacitors to achieve a rate of 96kbps error-free data transmission. Each driver and receiver can be used independently.
