DESCRIPTION

The ST207E is a 5 driver and 3 receiver devices

designedfor RS-232 and V.28 communications in

harsh enviroments. Each transmitter output and

(SSOP Package)

(TSSOPPackage)

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-232Especification.

The ST207E operates with four 0.1 F capacitors.

It cames in 24-pin SO and TSSOP packages.
