SLLS812B July 2007 – June 2021 TRS3232
The TRS3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with
±15-kV ESD protection terminal to terminal (serial-port connection terminals, including GND). The device meets the requirements of TIA/EIA-232-F and 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 one 3-V to 5.5-V supply. The device operates at data signaling rates up to 250 kbps and a maximum of 30-V/μs driver output slew rate. Outputs are protected against shorts to ground.
