What are the key features of TRS202ID?
- Dual RS-232 driver and receiver (2/2 full-duplex) compliant with EIA-232-F / TIA-232-F standards, enabling direct microcontroller UART to RS-232 interface without discrete level-shifting components
- Schmitt-trigger receiver inputs with ±200 mA maximum input current tolerance for robust noise rejection on long RS-232 cable runs in industrial serial communication applications
- Integrated charge-pump voltage doubler requiring only external 100 nF capacitors to generate RS-232 ±5V to ±15V levels from a single 3.3V or 5V supply in a compact 16-pin SOIC package
What is TRS202ID used for?
The TRS202ID is used in embedded systems requiring RS-232 serial port interfaces for industrial instruments, barcode scanners, POS terminals, and PLCs communicating with legacy RS-232 hosts. Its dual-channel 2-driver/2-receiver architecture supports simultaneous full-duplex communication on two independent RS-232 lines from a single IC, reducing BOM count in multi-port serial designs. Panel-mount HMI modules and data-acquisition systems also rely on this device for EIA-232-F compliant long-distance serial links up to 15 meters.

Frequently Asked Questions
How many independent RS-232 channels does the TRS202ID support in full-duplex mode, and what logic supply voltage does it accept?
The TRS202ID supports 2 independent full-duplex RS-232 channels, each with one driver and one receiver, allowing simultaneous bidirectional communication on 2 separate RS-232 ports. It operates from a 3V to 5.5V single logic supply, using an internal charge pump to generate the ±5V to ±15V output swing required by EIA/TIA-232-F without a separate bipolar power supply.
Why does the TRS202ID use Schmitt-trigger receiver inputs, and how does this benefit noisy industrial serial cable environments?
The TRS202ID receiver inputs use Schmitt-trigger hysteresis with a typical input threshold band of approximately 0.5V, which prevents multiple edge transitions from slow-rising or noise-corrupted RS-232 signals on long cables exceeding 3 meters. In industrial environments with motor-drive EMI or ground potential differences of several volts, the Schmitt-trigger input rejects noise spikes below the hysteresis band, maintaining clean TTL-level output transitions for accurate UART byte decoding.
What external components does the TRS202ID require to generate RS-232 voltage levels from a 5V supply?
The TRS202ID requires four 100 nF (0.1 µF) ceramic capacitors connected to its charge-pump capacitor pins (C1+, C1-, C2+, C2-) to generate the internal ±10V charge-pump voltage needed for RS-232 driver output levels of ±5V minimum. No additional power supply or discrete boost converter is needed, making the total external capacitor count just 4 parts for a complete 2-channel RS-232 interface on a 3.3V or 5V embedded system board.
When should a designer select TRS202ID over a MAX232 or equivalent single-channel RS-232 transceiver?
TRS202ID is the correct selection when the design requires 2 independent RS-232 channels in a single package, avoiding the need for two separate MAX232 devices and saving approximately 30% board area in a 16-pin SOIC versus two 16-pin packages. Its TIA-232-F compliance ensures interoperability with legacy RS-232 equipment at data rates up to 120 kbps, while the Schmitt-trigger inputs provide superior noise immunity compared to standard MAX232 receivers in industrial cable environments.
