General Description

The TRSF3221E consists of one line driver, one line receiver, and a dual charge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-port connection pins, including GND).

The TRSF3221E provides the electrical interface between an asynchronous communication controller and the serial-port connector.

The charge pump and four small external capacitors allow operation from a single 3-V to 5.5-V supply.

Key Features

  • ESD protection for RS-232 pins.
  • ±15-kV Human-body model (HBM).
  • ±8-kV IEC 61000-4-2 Contact discharge.
