SLLS847E – JULY 2007 – REVISED NOVEMBER 2016 TRS202E 5-V Dual RS-232 Line Driver and Receiver With ±15-kV IEC ESD Protection
1 Features 3 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/Вµs driver output slew rate. 1 IEC61000-4-2 (Level 4) ESD Protection for
RS-232 Bus Pins:
– ±8-kV Contact Discharge
– ±15-k-V Air-Gap Discharge
– В±15-kV Human-Body Model …
