ST202EBD

Drivers, Receivers, Transceivers Overview

The ST202EBD is a dual-driver, dual-receiver RS-232 transceiver from the STMicroelectronics ST202E series. It operates on a single 5 V supply and supports data rates up to 230 kbps. The device features ±15 kV electrostatic discharge (ESD) protection on all RS-232 I/O pins. It utilizes four 0.1 µF external capacitors for charge pump operation, reducing board space and cost compared to 1 µF requirements. The component meets EIA/TIA-232E and CCITT V.28 specifications with a guaranteed slew rate range of 3 to 30 V/µs.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±15 kV ESD protection on transmitter outputs and receiver inputs for harsh environment resilience
• Single 5 V power supply operation with reduced external capacitor count (four 0.1 µF)
• Compliance with EIA/TIA-232E and CCITT V.28 standards at data rates up to 230 kbps

Drivers, Receivers, Transceivers Applications

• RS-232 communications in harsh environments
• V.28 serial interface implementations
• Industrial equipment requiring robust ESD protection

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'D' indicates the SOIC-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to procurement. Ensure the selected component matches the required temperature grade and pin configuration for the target PCB layout.

Drivers, Receivers, Transceivers Selection Notes

Select this component over standard ST202B variants when enhanced ESD protection is required for industrial or outdoor applications. The use of 0.1 µF capacitors distinguishes it from the ST232E series which requires 1 µF capacitors. Verify that the 230 kbps maximum data rate and 3–30 V/µs slew rate meet the system timing requirements.

Drivers, Receivers, Transceivers Part Context

The ST202EBD belongs to the ST202E family, which includes ST202EB, ST202EC, ST232EB, and ST232EC. These devices are designed for RS-232 and V.28 communications. The 'E' designation signifies enhanced ESD protection capabilities compared to earlier generations. The part is an active product within STMicroelectronics' standard interface IC portfolio.

Drivers, Receivers, Transceivers Replacement Considerations

ST202BDR serves as a functional substitute but lacks the ±15 kV ESD protection. ST202EBTR offers identical electrical characteristics in a TSSOP-16 package instead of SOIC-16. ST232EBD provides similar functionality but requires 1 µF capacitors instead of 0.1 µF.
