3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver With +/-15-kV ESD Protection

 

Recommended alternative parts

  • TRS3253E  -  This device has a higher data rate, and an extended Vcc range (1.8V) and a 3.5 channel configuration.
  • TRSF3232  -  This device has a higher data rate, but no IEC 61000-4-2 support.

Description

The TRS3232E device consists of two line drivers, two-line receivers, and a dual charge-pump circuit with ±15-kV IEC 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 3-V to 5.5-V supply. The devices operate at data signaling rates up to 250 kbps and a maximum of 30-V/µs driver output slew rate.
