The TRS3232ECDW device consists of two line drivers, two-line receivers, and a dualcharge-pump circuit with ±15-kV IEC ESD protection pin to pin (serial-port connection pins,including GND).
The device meets the requirements of TIA/EIA-232-F and provides the electrical interfacebetween an asynchronous communication controller and the serial-port connector. The charge pump andfour small external capacitors allow operation from a single 3-V to 5.5-V supply. The devicesoperate at data signaling rates up to 250 kbps and a maximum of 30-V/μs driver output slewrate.
