| ST202EB - ST202EC ST232EB - ST232EC 15 kV ESD protected 5 V RS-232 transceiver Features ESD protection for RS-232 I/O pins: 15 kV human body model Guaranteed 230 kbps date rate Guaranteed slew rate range 3 to 30 V/ms Operate from a single 5 V power supply SOP SOP Large Description 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 F capacitors, while the ST202E operates with four 0.1 F capacitors, further reducing cost and board space.
