DESCRIPTION
The ST207E is a 5 driver and 3 receiver devices designedforRS-232 and V.28 communicationsin harsh enviroments. Each transmitter output and receiver input is protected against±15KV electrostaticdischarge (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 accordancewith the EIA/TIA-232Especification.
The ST207E operateswith four 0.1µF capacitors. It cames in 24-pinSO and TSSOPpackages.
