ST ST202EB - ST202EC ST232EB - ST232EC ± 15 kV ESD protected 5 V RS-232 transceiver handbook
The ST202E/ST232E are a 2 driver 2 receiver devices designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ± 15 kV electrostatic discharge (ESD) shocks. The drivers meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 230 kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST202E/232E use a single 5 V supply voltage. The ST232E operates with four 1 µF capacitors, while the ST202E operates with four 0.1 µF capacitors, further reducing cost and board space.
