What are the key features of TRS3232ECD?
- ±15 kV ESD protection on all RS-232 I/O pins protects against harsh industrial and field environments
- Wide supply range of 3 V to 5.5 V with optional 5 V operation eliminates the need for a dedicated 5 V rail
- Integrated charge-pump capacitors generate ±5 V RS-232 output swings from a single low-voltage supply
- Schmitt-trigger receiver inputs provide superior noise immunity in long-cable or noisy RS-232 links
What is TRS3232ECD used for?
TRS3232ECD is widely used in industrial automation equipment, handheld terminals, and embedded controllers that require RS-232 serial communication from a 3.3 V supply. The ±15 kV ESD rating makes it robust enough for field-wiring connections in PLCs, barcode scanners, and ruggedized instrumentation. It also serves in USB-to-RS-232 bridge boards and microcontroller evaluation platforms where dual UART channels are needed.

Frequently Asked Questions
How does TRS3232ECD achieve RS-232 output swing from a 3.3 V supply?
TRS3232ECD integrates a charge-pump voltage doubler and inverter that generates internal ±5 V rails from a 3 V to 5.5 V supply. These internal rails drive the 2 RS-232 transmitter outputs to the ±5 V levels required by TIA-232-F and V.28 standards, all without an external DC-DC converter. Only small 100 nF charge-pump capacitors are needed externally.
What level of ESD protection does TRS3232ECD provide on RS-232 lines, and which standard covers this?
TRS3232ECD provides ±15 kV human-body-model ESD protection on all RS-232 driver output and receiver input pins. This exceeds the IEC 61000-4-2 contact discharge level of ±4 kV and suits direct connection to field wiring or long RS-232 cables up to several meters. The protection is built into the silicon, so no external TVS diodes are required on the 16-pin SOIC design.
Can TRS3232ECD replace a 5 V-only MAX232 in a 3.3 V microcontroller system without hardware changes?
TRS3232ECD is functionally pin-compatible with the industry-standard RS-232 transceiver in a 16-pin SOIC footprint and operates down to 3 V, making it a drop-in replacement for 5 V MAX232 designs running on a 3.3 V rail. The charge-pump capacitor values (typically 100 nF) may need adjustment versus the 1 µF caps used in original MAX232 designs, but the PCB layout remains the same.
