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.
