General Description

The TRS3253E device is a three-driver and fivereceiver RS-232 interface device, with split supply pins for mixed-signal operations without needing an external voltage translator.

All RS-232 inputs and outputs are protected to ±15 kV using the IEC 610004-2 Air-Gap Discharge method, ±8 kV using the IEC 61000-4-2 Contact Discharge method, and ±15 kV using the Human Body Model.

The charge pump requires only four capacitors for operation from a single 3.3-V or 5-V supply.

Key Features

  • 1 VL Pin for Compatibility With Mixed-Voltage Systems Down to 1.8 V on Logic Side.
  • Enhanced ESD Protection on RIN Inputs and DOUT Outputs.
  • ±15-kV IEC 61000-4-2 Air-Gap Discharge.
  • ±8-kV IEC 61000-4-2 Contact Discharge.
  • ±15-kV Human Body Model.
  • Low 300-μA Supply Current.
  • Specified 1000-kbps Data Rate.
  • Auto Powerdown Plus Feature 2.
