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
P

(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.
µ
The ST207E operates with four 0.1 F capacitors.
It cames in 24-pin SO and TSSOP packages.
