ST207E ± 15KV ESD PROTECTED 5V RS-232 TRANSCEIVER ■ ■ ■ ■ ■ ESD PROTECTION FOR RS-232 I/O PINS: ±15 KV HUMAN BODY MODEL 230kbps DATE RATE GUARANTEED SLEW RATE 3V/µs (Min) OPERATES FROM A SINGLE 5V POWER SUPPLY PACKAGED IN SO-24, SSO-24 AND TSSOP24 DESCRIPTION The ST207E is a 5 driver and 3 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 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 came in 24-pin SO and TSSOP packages.
