Applications
The SP3222ECT-L/TR is designed for RS-232 serial communication interfaces in embedded systems, industrial controllers, and portable devices that require 3 V to 5.5 V operation. Its 2-driver/2-receiver architecture makes it suitable for point-to-point serial links in modems, barcode scanners, handheld terminals, and medical instruments. The small SOIC-18 footprint and low power consumption make it a preferred choice in compact and battery-operated designs needing EIA-232 compliance.

Frequently Asked Questions
What supply voltage range does the SP3222ECT-L/TR support for RS-232 operation?
The SP3222ECT-L/TR operates from a 3 V to 5.5 V single supply, making it compatible with both 3.3 V and 5 V logic systems. This wide voltage range enables use in modern low-voltage microcontroller designs while maintaining full EIA-232 and TIA-232 RS-232 compliance.
How many RS-232 driver and receiver channels does the SP3222ECT-L/TR provide, and what interface standards does it support?
The SP3222ECT-L/TR provides 2 RS-232 drivers and 2 receivers in a single 18-pin SOIC package. It is compliant with EIA-232, EIA-232-D, EIA-232-F, TIA-232, TIA-232-F, EIA-562, TIA-562, V.24, and V.28 serial interface standards, covering a broad range of legacy and modern RS-232 applications.
What makes the SP3222ECT-L/TR suitable for noise-sensitive or industrial RS-232 serial links?
The SP3222ECT-L/TR uses Schmitt trigger inputs on all receiver channels, which provide hysteresis of typically 0.5 V to reject noise and signal reflections on RS-232 lines. This improves communication reliability in industrial environments with electromagnetic interference, long cable runs, or poorly terminated serial links.
When would a designer choose the SP3222ECT-L/TR over a 5 V-only RS-232 transceiver?
Designers choose the SP3222ECT-L/TR when the system supply is 3.3 V or when mixing 3.3 V and 5 V logic, since it accepts 3 V to 5.5 V input. A 5 V-only transceiver cannot interface directly with 3.3 V microcontroller IO without level-shifting, adding board space and cost, while the SP3222ECT-L/TR eliminates that overhead with its 2-driver/2-receiver low-power design.
