DESCRIPTION/ORDERING INFORMATION
The TRS202E device consists of two line drivers, two line receivers, and a dual charge-pump circuit. TRS202E
has IEC61000-4-2 (Level 4) 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/ms driver output slew rate.
The TRS202E can work with both 0.1-mF or 1-mF external capacitors.
