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

 

Recommended alternative parts

  • TRS3232E  - The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device. 

Description

The MAX3232E 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 kbit/s and a maximum of 30-V/µs driver output slew rate.
