Recommended alternative parts

  • SN65C3221E  -  3-V To 5.5-V Single Channel RS-232 1 Mbit/s Line Driver/Receiver
  • SN65C3238E  -  3-V to 5.5-V Multichannel RS-232 Line Driver/Receiver With +/-15-kV ESD (HBM) Protection

Description

The SN65C3232E and SN75C3232E consist of two line drivers, two line receivers, and a dual charge-pump circuit with ±15-kV ESD protection pin to pin (serial-port connection pins, including GND). These devices provide 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 1 Mbit/s and a driver output slew rate of 14 V/µs to 150 V/µs.
