Features and Applications

The ST202ECDR is a 2 driver 2 receiver devices designed for RS-232 and V.28 communications in harsh environments. Each transmitter output and receiver input is protected against ± 15 kV electrostatic discharge (ESD) shocks.

The drivers meet all EIA/TIA-232E and CCITT V.28 specifications at data rates up to 230 kbps, when loaded in accordance with the EIA/TIA-232E specification. The ST202E/232E use a single 5 V supply voltage. The ST232E operates with four 1 μF capacitors, while the ST202E operates with four 0.1 μF capacitors, further reducing cost and board space.


  • ESD protection for RS-232 I/O pins:
  • ± 15 kV human body model
  • Guaranteed 230 kbps date rate
  • Guaranteed slew rate range 3 to 30 V/ms
  • Operate from a single 5 V power supply
