ST207E ± 15KV ESD PROTECTED 5V RS-232 TRANSCEIVER PRELIMINARY DATA ■ ■ ■ ■ ■ ESD PROTECTION FOR RS-232 I/O PINS: ± 15 KV HUMAN BODY MODEL GUARANTEED 120kbpsDATE RATE LapLink COMPATIBLE GUARANTEED SLEW RATE 3V/µs (Min) OPERATE FROM A SINGLE 5V POWER SUPPLY PACKAGED IN SO-24, SSO-24 AND TSSOP24 PACKAGES DESCRIPTION The ST207E is a 5 driver and 3 receiver devices designed for RS-232 and V.28 communications in harsh enviroments. Each transmitter output and receiver input is protected against ±15KV electrostatic discharge (ESD) shocks. The drivers and receivers of the ST207E meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 120Kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST207E operates with four 0.1µF capacitors. It cames in 24-pin SO and TSSOP packages.
