What are the key features of TRSF3238IDWRG4?
- Wide supply voltage range of 3 V to 5.5 V with full 5 V compatibility, enabling seamless use in both 3.3 V low-power systems and legacy 5 V RS-232 designs
- 5-driver and 5-receiver channel count in a single 28-pin SOIC package, reducing board area versus multi-chip solutions for multi-port serial communication
- Schmitt-trigger inputs on all receiver channels provide improved noise immunity on long cable runs and in electrically noisy industrial environments
What is TRSF3238IDWRG4 used for?
The TRSF3238IDWRG4 is ideal for embedded systems requiring multiple RS-232 serial ports, such as industrial PLCs, medical instrumentation, and point-of-sale terminals that connect to legacy peripherals. Its 3 V to 5.5 V supply range makes it a practical bridge between modern low-voltage microcontrollers and EIA-232-compliant equipment in communication and test systems.

Frequently Asked Questions
How does the TRSF3238IDWRG4 handle both 3.3 V and 5 V system designs in the same RS-232 application?
The TRSF3238IDWRG4 operates from a supply voltage of 3 V to 5.5 V, meaning it powers correctly in 3.3 V microcontroller systems and legacy 5 V designs without any hardware changes. This dual-voltage compatibility simplifies board redesigns and reduces inventory complexity when migrating between voltage domains.
What is the channel count and package configuration of the TRSF3238IDWRG4?
The TRSF3238IDWRG4 integrates 5 RS-232 drivers and 5 RS-232 receivers in a single 28-pin SOIC package, delivering 5 full-duplex EIA-232 channels from one IC. This high channel density minimizes PCB footprint in multi-port serial communication designs.
Which industrial or embedded applications are best served by the Schmitt-trigger inputs on the TRSF3238IDWRG4 receivers?
Industrial control panels, factory automation equipment, and medical devices operating in high-EMI environments benefit most from Schmitt-trigger receiver inputs. The hysteresis built into each input ensures clean digital transitions even when EIA-232 signals arrive with noise levels up to several hundred millivolts of interference on cable lengths exceeding 5 meters.
