What are the key features of TRS232ECDR?
- 2-TX / 2-RX RS-232 transceiver meets EIA-232-F and TIA-232-F standards from a single 5 V supply
- Schmitt-trigger receiver inputs provide noise immunity for long cable runs and electrically noisy environments
- Minimum 10 V output swing ensures reliable RS-232 signaling at full EIA-232-F voltage compliance
What is TRS232ECDR used for?
TRS232ECDR is used in embedded systems and industrial equipment requiring RS-232 serial port interfaces, such as PLC communication modules, barcode scanner controllers, and measurement instrument front panels. The dual-channel configuration supports full-duplex point-to-point serial links or two independent half-duplex channels simultaneously. Its 16-pin SOIC package suits compact PCB designs with space for standard SMD assembly.

Frequently Asked Questions
What voltage swing does TRS232ECDR produce on its RS-232 transmit outputs?
TRS232ECDR guarantees a minimum output swing of ±10 V on the transmitter outputs when loaded per EIA-232-F specification, ensuring compliance with the RS-232 standard that requires signal levels between ±3 V and ±15 V. This full-swing output maintains reliable signaling across cable lengths up to 15 meters at standard baud rates.
How many independent serial channels can TRS232ECDR handle simultaneously in a full-duplex application?
TRS232ECDR integrates 2 transmitters and 2 receivers in a single 16-pin SOIC package, supporting 2 full-duplex RS-232 channels simultaneously or 2 half-duplex links. This dual-channel architecture allows a single IC to implement a complete 2-port serial interface for devices like modems, GPS modules, or barcode readers.
Why do the Schmitt-trigger inputs on TRS232ECDR benefit long-cable RS-232 installations?
Schmitt-trigger receiver inputs provide approximately 0.5 V of hysteresis, preventing false triggering caused by slow signal edges or noise induced on cables longer than 5 meters. This is especially important in industrial environments where 50 Hz or 60 Hz interference can couple onto unshielded RS-232 cables and cause data errors without hysteresis protection.
Is TRS232ECDR suitable as a drop-in replacement for MAX232-compatible transceivers in existing designs?
TRS232ECDR is pin-compatible with standard dual-RS-232 transceiver footprints that use a 16-pin SOIC package with the same 2-TX/2-RX topology. It operates from a single 5 V supply and uses internal charge-pump capacitors of 100 nF or larger, matching the same external capacitor configuration used by MAX232 and similar devices.
