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.
