What are the key features of TRS232EIDR?
- IEC 61000-4-2 Level 4 ESD protection up to ±15 kV on RS-232 I/O pins prevents damage from electrostatic discharge in unprotected port environments
- Integrated charge pump capacitors keep external component count low with only 4 small capacitors needed to generate ±10 V RS-232 drive voltages from a 3.3 V supply
- Schmitt trigger receiver inputs with 0.5 V hysteresis reject cable noise and slow signal edges common on long RS-232 cables
What is TRS232EIDR used for?
The TRS232EIDR is designed for RS-232 serial port implementations in industrial equipment, medical devices, and embedded controllers where electrostatic discharge on connector pins is a real-world reliability risk. Its 2 driver and 2 receiver channels cover the most common DTE-to-DCE configurations used in legacy serial peripherals, modems, and barcode readers. The SOIC-16 package and 3.3 V single-supply operation make it straightforward to integrate into modern microcontroller boards that need backward-compatible RS-232 connectivity.

Frequently Asked Questions
What level of ESD protection does TRS232EIDR provide on its RS-232 interface pins?
The TRS232EIDR meets IEC 61000-4-2 Level 4 requirements, providing up to ±15 kV contact and air-gap ESD protection on the RS-232 driver output and receiver input pins. This level of protection is significantly higher than the ±2 kV of unprotected generic RS-232 transceivers, reducing field failures in industrial panels and medical equipment where operators frequently touch serial connector pins.
Can TRS232EIDR operate from a 3.3 V supply and still meet RS-232 output swing requirements?
Yes, the TRS232EIDR operates from a single 3.3 V supply and uses an integrated charge pump with 4 external capacitors to generate the ±10 V swing required by EIA-232-F. The minimum output swing is specified at 10 V, which comfortably exceeds the ±5 V threshold required for valid RS-232 logic levels, ensuring compatibility with all standard RS-232 receivers over cable lengths up to 15 m.
How many RS-232 channels are integrated in TRS232EIDR, and which pin count package does it use?
The TRS232EIDR integrates 2 independent RS-232 driver channels and 2 independent receiver channels, providing a complete dual-port transceiver in a 16-pin SOIC package. This configuration covers the minimum TxD, RxD, RTS, and CTS signal set needed for hardware flow-controlled serial communication, which is commonly required by industrial modems and GPS receiver modules.
When is TRS232EIDR preferred over a basic MAX232 for a rugged field device design?
The TRS232EIDR is preferred over a standard MAX232 in rugged field devices because it adds IEC 61000-4-2 Level 4 ESD protection that the MAX232 lacks by default, eliminating the need for separate TVS diodes on each RS-232 pin. For a 2-channel port design this can save 4 to 8 external protection components and reduce PCB area by 20 mm² to 40 mm², while the Schmitt trigger inputs also improve noise immunity compared to the MAX232 single-threshold comparators.
