DESCRIPTION/ORDERING INFORMATION
The TRS207 consists of five line drivers, three line receivers, and a dual charge-pump circuit with ±15-kV 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 interface between an asynchronous communication controller and the
serial-port connector. The charge pump and four small external capacitors allow operation from a single 5-V
supply. The devices operate at data signaling rates up to 120 kbit/s and a maximum of 30-V/μs driver output
slew rate.
