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 0.1F capacitors. It cames in 24-pin SO and TSSOP packages. ORDERING CODES
