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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-16 |+| Category | Comm/UART |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `TRS3232EIPWR`+- `TRS3232EIPWRCPW`+- `TRS3232EIPWRCPWR`+- `TRS3232EIPWRID`+- `TRS3232EIPWRIDR`+- `TRS3232EIPWRCD`+- `TRS3232EIPWRCDR`+- `TRS3232EIPWRIDB`+- `TRS3232EIPWRIDBR`+- `TRS3232EIPWRCDB`+- `TRS3232EIPWRCDBR`+- `TRS3232EIPWRIDW`+- `TRS3232EIPWRIDWR`+- `TRS3232EIPWRCDW`+- `TRS3232EIPWRCDWR`+- `TRS3232EIPWRIRGT`+- `TRS3232EIPWRIRGTR`+- `TRS3232EIPWRCRGT`+- `TRS3232EIPWRCRGTR`++## CAD (KiCad official)++- Symbol: `TRS3232EIPWR`+- Footprint: `Package_SO:TSSOP-16_4.4x5mm_P0.65mm`+- 3D model: TSSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](docs/trs3232eipwr-datasheet.pdf) (38 pp, sha256 `9773be544db0bcb1`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
