Key Features

  • ±15kV IEC ESD protection on RS-232 I/O lines guards against electrostatic discharge in harsh industrial and field-deployed environments
  • 1Mbit/s maximum data rate enables high-speed RS-232 serial communication well beyond the standard 115.2kbps for faster legacy interface applications
  • 3V to 5.5V supply range with Schmitt trigger inputs supports both 3.3V low-power and 5V legacy system designs from a single device
  • Dual-channel full-duplex transceiver integrates two drivers and two receivers in a single 16-pin SOIC package, minimizing BOM count

Applications

The TRSF3232EID is used in industrial equipment, embedded systems, and test instruments that communicate over RS-232 serial interfaces with enhanced ESD protection for reliable operation in electrically noisy environments. Its 1Mbit/s throughput supports high-speed legacy serial connections to PLCs, barcode scanners, modems, and GPS modules. The wide 3V to 5.5V supply range makes it a convenient interface bridge between low-voltage microcontrollers and RS-232 equipment.

Frequently Asked Questions

What ESD protection level does the TRSF3232EID provide?

The TRSF3232EID provides ±15kV IEC ESD protection on its RS-232 interface pins. This high level of protection reduces the risk of device damage from electrostatic discharge during cable handling, hot-plugging, or operation in electrically noisy industrial environments.

What is the maximum data rate supported by the TRSF3232EID?

The TRSF3232EID supports RS-232 data rates up to 1Mbit/s, significantly exceeding the typical 115.2kbps of most RS-232 applications. This allows use in high-speed serial data transfer scenarios where faster legacy interface throughput is needed.

What supply voltage does the TRSF3232EID require?

The TRSF3232EID operates from a 3V to 5.5V supply voltage range. This flexibility allows it to interface with modern 3.3V microcontrollers and FPGAs as well as traditional 5V systems without requiring separate power supplies or level-shifting circuits.

What package is the TRSF3232EID available in?

The TRSF3232EID is housed in a 16-pin SOIC (Small Outline Integrated Circuit, JEDEC R-PDSO-G16) surface-mount package. This standard package is widely supported by PCB assembly equipment and offers good thermal and mechanical robustness for industrial applications.

How many RS-232 channels does the TRSF3232EID support?

The TRSF3232EID provides two independent RS-232 channels, each with a driver and receiver (2 drivers and 2 receivers total). This enables full-duplex communication on two separate RS-232 ports, making it suitable for multi-port serial interfaces in embedded systems.
