ST202E ST232E ± 15KV ESD PROTECTED 5V RS-232 TRANSCEIVER ■ ■ ■ ■ ESD PROTECTION FOR RS-232 I/O PINS: ± 15KV HUMAN BODY MODEL GUARANTEED 230kbps DATE RATE GUARANTEED SLEW RATE RANGE 3 to 30V/µs OPERATE FROM A SINGLE 5V POWER SUPPLY 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 ± 15KV electrostatic discharge (ESD) shocks. The drivers meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 230Kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST202E/232E use a single 5V supply voltage. The ST232E operates with four 1µF capacitors, while the ST202E operates with four 0.1µF capacitors, further reducing cost and board space.
