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 terminal of the voltage-doubler charge-pump capacitor C1 (0.1µF typical, 16V breakdown). Connects between C1+ and C1- to build the V+ rail (~2×VCC). |+| 2 | V+ | power_out | Charge-pump output, regulated to approximately +5.5V regardless of VCC over the +3.0V to +5.5V input range. Bypass to GND with a 0.1µF capacitor (C3). Absolute max +7V; |V+ - V-| must not exceed 13V. |+| 3 | C1- | passive | Negative terminal of the voltage-doubler charge-pump capacitor C1 (0.1µF typical). Paired with C1+ to generate V+. |+| 4 | C2+ | passive | Positive terminal of the inverting charge-pump capacitor C2 (0.1µF typical). Paired with C2- to generate the negative V- rail. |+| 5 | C2- | passive | Negative terminal of the inverting charge-pump capacitor C2 (0.1µF typical). Paired with C2+ to generate V-. |+| 6 | V- | power_out | Charge-pump output regulated to approximately -5.5V. Bypass to GND with a 0.1µF capacitor (C4). Absolute max -7V; |V+ - V-| must not exceed 13V. |+| 7 | T2OUT | output | RS-232 driver 2 output. Inverting level-shifted driver output; typical swing ±5.4V (min ±5.0V) into a 3kΩ load. Short-circuit and ±15kV ESD protected; tri-stated when device is shut down. |+| 8 | R2IN | input | RS-232 receiver 2 input. Accepts ±25V input range with ~5kΩ input resistance and ~0.3V hysteresis. Internal 5kΩ pulldown holds RxOUT HIGH when input is open. |+| 9 | R2OUT | output | TTL/CMOS receiver 2 output. Drives VOL ≤ 0.4V at 1.6mA and VOH ≥ VCC-0.6V at -1.0mA. Inverted with respect to R2IN. |+| 10 | T2IN | input | TTL/CMOS driver 2 input. Logic threshold LOW ≤ 0.8V, HIGH ≥ 2.0V (VCC=3.3V) or ≥ 2.4V (VCC=5.0V); ~250mV hysteresis. Inverted to T2OUT. |+| 11 | T1IN | input | TTL/CMOS driver 1 input. Logic threshold LOW ≤ 0.8V, HIGH ≥ 2.0V (VCC=3.3V) or ≥ 2.4V (VCC=5.0V); ~250mV hysteresis. Inverted to T1OUT. |+| 12 | R1OUT | output | TTL/CMOS receiver 1 output. Drives VOL ≤ 0.4V at 1.6mA and VOH ≥ VCC-0.6V at -1.0mA. Inverted with respect to R1IN. |+| 13 | R1IN | input | RS-232 receiver 1 input. Accepts ±25V input range with ~5kΩ input resistance and ~0.3V hysteresis. Internal 5kΩ pulldown holds RxOUT HIGH when input is open. |+| 14 | T1OUT | output | RS-232 driver 1 output. Inverting level-shifted driver output; typical swing ±5.4V (min ±5.0V) into a 3kΩ load. Short-circuit and ±15kV ESD protected. |+| 15 | GND | power_in | Device ground reference for logic and charge-pump return. |+| 16 | VCC | power_in | Positive supply, +3.0V to +5.5V (absolute max +6V). Decouple to GND with a 0.1µF bypass capacitor (C5) placed close to the pin. Typical no-load supply current ~0.3mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | MaxLinear |+| Package | SOIC-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `SP3232EBEN-LSP3232EBEN`+- `SP3232EBEN-L`+- `SP3232EBEN-LSP3232EBEN/TR`+- `SP3232EBEN-L/TR`+- `SP3232EBEN-LSP3232EBCN`+- `SP3232EBEN-LSP3232EBCN/TR`+- `SP3232EBEN-LSP3232EBCA`+- `SP3232EBEN-LSP3232EBCA/TR`+- `SP3232EBEN-LSP3232EBEA`+- `SP3232EBEN-LSP3232EBEA/TR`+- `SP3232EBEN-LSP3232EBCP`+- `SP3232EBEN-LSP3232EBEP`+- `SP3232EBEN-LSP3232EBCT`+- `SP3232EBEN-LSP3232EBCT/TR`+- `SP3232EBEN-LSP3232EBET`+- `SP3232EBEN-LSP3232EBET/TR`+- `SP3232EBEN-LSP3232EBCY`+- `SP3232EBEN-LSP3232EBCY/TR`+- `SP3232EBEN-LSP3232EBEY`+- `SP3232EBEN-LSP3232EBEY/TR`++## CAD (KiCad official)++- Symbol: `SP3232EBEN-L`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [MaxLinear datasheet](docs/sp3232eben-l-datasheet.pdf) (20 pp, sha256 `a5b7a7bff614aac4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
