What are the key features of TRS3227IDB?
- Wide 3 V to 5.5 V supply range supports both 3.3 V and 5 V logic systems without level-shifting circuitry
- ±15 kV ESD protection on RS-232 I/O pins guards against human-body model discharge events in industrial environments
- Schmitt-trigger inputs with EIA-232-F / TIA-232-F compliance ensure noise-immune reception on noisy serial communication lines
What is TRS3227IDB used for?
The TRS3227IDB is designed for single-channel RS-232 serial communication in industrial control systems, embedded microcontroller UART interfaces, and portable instruments that require reliable ±15 kV ESD-protected data links. Its 3 V to 5.5 V supply flexibility makes it easy to integrate alongside modern low-voltage microcontrollers or legacy 5 V processors without additional level translation. The 16-pin SOIC footprint suits both through-hole-adjacent prototyping and standard SMT production workflows.

Frequently Asked Questions
What supply voltage range does the TRS3227IDB support and why does that matter for 3.3 V systems?
The TRS3227IDB operates from 3 V to 5.5 V, allowing direct connection to 3.3 V microcontroller power rails without a separate regulator. This reduces BOM cost and simplifies PCB layout for modern low-voltage UART designs.
How much ESD protection do the RS-232 pins on the TRS3227IDB provide?
The RS-232 line pins are protected to ±15 kV using the human-body model, making the TRS3227IDB robust against electrostatic discharge in industrial or handheld equipment where connector mating can introduce high-voltage transients.
Which serial communication standards does the TRS3227IDB comply with?
The TRS3227IDB conforms to EIA-232-F, TIA-232-F, and V.28 standards, covering the full electrical specification for RS-232 signaling at data rates up to the standard maximum, with a single driver and 1 receiver channel.
When would you choose TRS3227IDB over a multi-channel RS-232 transceiver?
When the design only needs 1 RS-232 channel, such as a single debug UART port, the TRS3227IDB saves board space by fitting into a 16-pin SOIC rather than a larger 28-pin or 32-pin package used by 4-channel or 5-channel alternatives.
