TRS3232EIPWR

Texas Instruments · RS232 ICs · TSSOP-16

TRS3232EIPWR from Texas Instruments, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 C1+ passive Positive lead of charge-pump flying capacitor C1. Connect an external capacitor (0.1 µF at VCC = 3.3 V; 0.047 µF at VCC = 5 V) between C1+ and C1-.
2 V+ power_out Positive charge-pump output for external storage capacitor only (typically +5.5 V). Requires a 0.1 µF or 0.33 µF capacitor to GND per operating conditions.
3 C1- passive Negative lead of charge-pump flying capacitor C1.
4 C2+ passive Positive lead of charge-pump flying capacitor C2 (0.1 µF or 0.33 µF).
5 C2- passive Negative lead of charge-pump flying capacitor C2.
6 V- power_out Negative charge-pump output for external storage capacitor only (typically -5.5 V). Requires a 0.1 µF or 0.33 µF capacitor to GND.
7 DOUT2 output RS-232 line data output for channel 2 (to remote RS-232 system). Swings ±5 V nominal, drives 3-kΩ load; ±15-kV IEC air-gap / ±8-kV IEC contact ESD protected.
8 RIN2 input RS-232 line data input for channel 2 (from remote RS-232 system). Accepts ±25 V input; ±15-kV IEC air-gap / ±8-kV IEC contact ESD protected.
9 ROUT2 output Logic-level (CMOS) data output for channel 2 (to UART). Output swings 0 V to VCC.
10 DIN2 input Logic-level (CMOS) data input for channel 2 (from UART). VIH ≥ 2 V at VCC = 3.3 V, ≥ 2.4 V at VCC = 5 V; VIL ≤ 0.8 V.
11 DIN1 input Logic-level (CMOS) data input for channel 1 (from UART).
12 ROUT1 output Logic-level (CMOS) data output for channel 1 (to UART).
13 RIN1 input RS-232 line data input for channel 1 (from remote RS-232 system). ±15-kV IEC air-gap / ±8-kV IEC contact ESD protected.
14 DOUT1 output RS-232 line data output for channel 1 (to remote RS-232 system). ±15-kV IEC air-gap / ±8-kV IEC contact ESD protected.
15 GND power_in Ground reference for supply and signals.
16 VCC power_in Supply voltage input, 3.0 V to 5.5 V. Bypass with a minimum 1-µF capacitor to GND to meet the specified IEC 61000-4-2 rating.

CAD (KiCad official)

  • Symbol: TRS3232EIPWR
  • Footprint: Package_SO:TSSOP-16_4.4x5mm_P0.65mm
  • 3D model: TSSOP-16 (KiCad packages3D, STEP)
  • 3D model files: trs3232eipwr-etched.step / trs3232eipwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); trs3232eipwr.step / trs3232eipwr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (38 pp, sha256 9773be544db0bcb1, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
