TRS202E (ACTIVE)

5-V Dual RS-232 Line Driver/Receiver With +/-15 kV ESD Protection

 

Description

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/µs driver output slew rate.
