DESCRIPTION The ST207E is a 5 driver and 3 receiver devices designed f or 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 a ll 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 .
