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 the positive terminal of C1 (0.1-0.2 µF) between C1+ (pin 1) and C1- (pin 3). |+| 2 | V+ | power_out | Positive charge-pump output (~+2×VCC). Connect a storage capacitor C3 (0.1-0.2 µF) from V+ to GND; do not use this rail to power external circuitry. |+| 3 | C1- | passive | Negative lead of charge-pump flying capacitor C1. Pairs with C1+ (pin 1). |+| 4 | C2+ | passive | Positive lead of charge-pump flying capacitor C2. Connect C2 (0.1-0.2 µF) between C2+ (pin 4) and C2- (pin 5). |+| 5 | C2- | passive | Negative lead of charge-pump flying capacitor C2. Pairs with C2+ (pin 4). |+| 6 | V- | power_out | Negative charge-pump output (~-2×VCC, min -7 V absolute). Connect a storage capacitor C4 (0.1-0.2 µF) from V- to GND; storage-capacitor use only. |+| 7 | TOUT2 | output | RS-232 driver 2 output. Swings typically ±5.4 V into a 3 kΩ load with 6-30 V/µs slew rate; short-circuit current limited to ±60 mA. |+| 8 | RIN2 | input | RS-232 receiver 2 input. Accepts ±15 V RS-232 levels through a 3-7 kΩ input resistance with a 1.25 V typical switching threshold and 0.3 V hysteresis. |+| 9 | ROUT2 | output | TTL/CMOS receiver 2 output. Drives VCC/GND rails with VOL ≤ 0.3 V at -1.5 mA and VOH ≥ VCC-0.3 V at 1.5 mA. |+| 10 | TIN2 | input | TTL/CMOS driver 2 input. VIL ≤ 0.8 V; VIH ≥ 2.0 V (VCC=3.3 V) or ≥ 2.4 V (VCC=5.0 V). Leakage -1 to 15 µA. |+| 11 | TIN1 | input | TTL/CMOS driver 1 input. VIL ≤ 0.8 V; VIH ≥ 2.0 V (VCC=3.3 V) or ≥ 2.4 V (VCC=5.0 V). |+| 12 | ROUT1 | output | TTL/CMOS receiver 1 output. Drives VCC/GND rails with VOL ≤ 0.3 V at -1.5 mA and VOH ≥ VCC-0.3 V at 1.5 mA. |+| 13 | RIN1 | input | RS-232 receiver 1 input. Accepts ±15 V RS-232 levels through a 3-7 kΩ input resistance with a 1.25 V typical threshold and 0.3 V hysteresis. |+| 14 | TOUT1 | output | RS-232 driver 1 output. Swings typically ±5.4 V into a 3 kΩ load with 6-30 V/µs slew rate; short-circuit current limited to ±60 mA. |+| 15 | GND | power_in | Ground reference for VCC, logic-side pins, and the RS-232 outputs. |+| 16 | VCC | power_in | Supply voltage input, +3.0 V to +5.5 V (absolute max 6 V). Bypass to GND with a 0.1 µF ceramic capacitor. Supply current typically 1.2 mA no-load, up to 15 mA at max load. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 3PEAK |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `TPT3232E-TS3R`+- `TPT3232E-TS3RSS3R`+- `TPT3232E-TS3RSO3R`++## CAD (KiCad official)++- Symbol: `TPT3232E-TS3R`+- 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:** [3PEAK datasheet](docs/tpt3232e-ts3r-datasheet.pdf) (10 pp, sha256 `b5563e7757b5cb9d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
