Key Features

  • ±15kV ESD protection on RS-232 I/O pins for robust system reliability
  • Operates from 3V to 5.5V supply, also compatible with 5V systems
  • Dual RS-232 drivers and receivers in a compact 16-pin SOIC package
  • Schmitt trigger inputs for improved noise immunity
  • Compliant with EIA-232-F, TIA-232-F, and V.28 interface standards

Applications

The TRS3232CDR is widely used in industrial automation and embedded systems for reliable serial communication between microcontrollers and RS-232 peripherals. It is ideal for applications such as point-of-sale terminals, medical instruments, and telecom equipment where robust ESD protection and low-voltage operation are critical. Its dual driver/receiver configuration also makes it suitable for full-duplex RS-232 data links in harsh electrical environments.
