ST202EB, ST202EC, ST232EB, ST232EC 15 kV ESD-protected 5 V RS-232 transceiver Datasheet - production data Description The ST202EB, ST202EC, ST232EB, and ST232EC are two-driver, two-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 ST202EB, ST202EC, ST232EB, and ST232EC use a single 5 V supply Features voltage. ESD protection for RS-232 I/O pins: 15 kV The ST232EB and ST232EC operate with four human body model 1 F capacitors, while the ST202EB and Guaranteed 230 kbps date rate ST202EC operate with four 0.1 F capacitors, Guaranteed slew rate range 3 to 30 V/s further reducing cost and board space. Operates from a single 5 V power supply March 2017 DocID6900 Rev 18 1/18 www.st.com This is information on a product in full production.
