3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver - MAX3232

MAX3232 (ACTIVE)

3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver

 

Recommended alternative parts

  • TRS3232E  -  The device has the SAME FUNCTIONALITY/PINOUT as the compared device but includes enhanced IEC61000-4-2 ESD Protection. TI Recommends the TRS3232E in new designs
  • TRS3232  - The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device. 

Description

The MAX3232 device consists of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection terminal to terminal (serial-port connection terminals, 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.
