Key Features
- 3 V to 5.5 V supply range with 5 V compatibility, enabling RS-232 serial communication from low-voltage MCU systems without a dedicated 5 V rail
- Dual driver and dual receiver (2+2) configuration with Schmitt trigger inputs for superior noise immunity on long RS-232 cables up to ±15 V
- EIA-232-F and TIA-232-F compliant in a 20-pin SOIC package, with 1 µA maximum high-level input current for minimal bus loading
Applications
TRS3222IDB is used in embedded systems requiring serial RS-232 communication between 3.3 V MCUs and legacy RS-232 equipment such as industrial terminals, barcode scanners, and GPS modules. Its 3 V to 5.5 V supply range eliminates the need for a separate 5 V power rail, simplifying power supply design in portable and battery-backed industrial controllers. The Schmitt trigger receiver inputs improve signal integrity on electrically noisy factory floors where RS-232 cables run alongside power wiring.

Frequently Asked Questions
What supply voltage range does TRS3222IDB support and how does it interface with 3.3 V MCUs?
TRS3222IDB operates from a 3 V to 5.5 V supply, allowing direct interfacing with 3.3 V MCU UART pins while converting signal levels to the ±5 V to ±15 V RS-232 standard required by EIA-232-F compliant serial equipment.
How many drivers and receivers does TRS3222IDB provide and what is the input current specification?
TRS3222IDB integrates 2 RS-232 line drivers and 2 receivers in a single 20-pin SOIC package, with a maximum high-level input current of 1 µA (0.000001 A), minimizing loading on the connected RS-232 bus.
Why does TRS3222IDB use Schmitt trigger inputs and what noise margin improvement results?
The Schmitt trigger inputs on TRS3222IDB provide hysteresis to clean up slow-rising or noisy RS-232 signals, improving noise rejection on cable runs exceeding 3 meters in industrial environments where electromagnetic interference can corrupt serial data.
In which legacy serial interface migration scenarios is TRS3222IDB the right RS-232 transceiver choice?
TRS3222IDB suits designs migrating from 5 V RS-232 logic to 3.3 V platforms because its 3 V to 5.5 V supply range and dual 2-channel configuration replace older 5 V-only transceivers with a single device that also operates at 5 V for backward compatibility.
