Recommended alternative parts

  • TRSF3232  -  The industrial temp version is an EXACT EQUIVALENT in functionality and parametrics to the compared device.
  • SN65C3232E  -  TI recommends the SN65C3232E in new designs. SN65C3232E is an improved direct drop-in replacement for the SN65C3232.

Description

The SN65C3232 and SN75C3232 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 24 V/µs to 150 V/µs.

Features

  • Operate With 3-V to 5.5-V VCC Supply
  • Operate up to 1 Mbit/s
  • Low Supply Current . . . 300 µA Typical
  • External Capacitors ...4 × 0.1 µF
  • Accept 5-V Logic Input With 3.3-V Supply
  • Latch-Up Performance Exceeds 100 mA Per JESD 78, Class II
  • RS-232 Bus-Pin ESD Protection Exceeds ±15 kV Using Human-Body Model (HBM)
  • Applications
    • Battery-Powered Systems, PDAs, Notebooks, Laptops, Palmtop PCs, and Hand-Held Equipment
