The TRS202 device consists of two line drivers, two 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 device operates at data signaling rates up to 120 kbit/s and a maximum of 30-V/

μs driver output

slew rate.
