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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
