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 end of the voltage-doubler charge-pump capacitor C1. Connect an external flying capacitor (0.1µF typical at 3.3V, 0.047µF at 5V) between C1+ (pin 1) and C1- (pin 3). |+| 2 | V+ | power_out | Positive voltage produced by the internal charge pump (approximately +2×VCC). Bypass to GND with a reservoir capacitor (0.1µF to 0.47µF depending on VCC). Absolute max +7V; V+ to V- difference must not exceed 13V. |+| 3 | C1- | passive | Negative end of the voltage-doubler charge-pump capacitor C1. Paired with C1+ (pin 1) to form the doubler flying cap. |+| 4 | C2+ | passive | Positive end of the inverting charge-pump flying capacitor C2. Connect an external cap (0.1µF to 0.33µF depending on VCC) between C2+ (pin 4) and C2- (pin 5). |+| 5 | C2- | passive | Negative end of the inverting charge-pump flying capacitance. Paired with C2+ (pin 4). |+| 6 | V- | power_out | Negative voltage generated by the internal inverting charge pump (approximately -2×VCC). Bypass to GND with a reservoir capacitor. Absolute max -7V; V+ to V- difference must not exceed 13V. |+| 7 | DOUT2 | output | RS-232 driver output for channel 2. Swings between V+ and V- to drive an RS-232 line. Short-circuit protected to GND (Ios ±60 mA typ). ESD-protected to ±15 kV HBM / IEC 61000-4-2 air discharge. |+| 8 | RIN2 | input | RS-232 receiver input for channel 2. Accepts ±25V RS-232 line levels via a built-in 5 kΩ (3-7 kΩ) input resistance to ground. ESD-protected to ±15 kV HBM. |+| 9 | ROUT2 | output | TTL/CMOS receiver output for channel 2. Drives VCC-referenced logic (VOH ≥ VCC-0.6 at -1 mA, VOL ≤ 0.4 mV at 1.6 mA). Output goes high when RIN2 is open-circuit. |+| 10 | DIN2 | input | TTL/CMOS driver input for channel 2. VIH ≥ 2.0V (VCC=3.3V) or 2.4V (VCC=5V); VIL ≤ 0.8V. Inverted through the driver to DOUT2. |+| 11 | DIN1 | input | TTL/CMOS driver input for channel 1. VIH ≥ 2.0V (VCC=3.3V) or 2.4V (VCC=5V); VIL ≤ 0.8V. Inverted through the driver to DOUT1. |+| 12 | ROUT1 | output | TTL/CMOS receiver output for channel 1. Drives VCC-referenced logic (VOH ≥ VCC-0.6 at -1 mA, VOL ≤ 0.4 mV at 1.6 mA). Output goes high when RIN1 is open-circuit. |+| 13 | RIN1 | input | RS-232 receiver input for channel 1. Accepts ±25V RS-232 line levels via a built-in 5 kΩ (3-7 kΩ) input resistance to ground. ESD-protected to ±15 kV HBM. |+| 14 | DOUT1 | output | RS-232 driver output for channel 1. Swings between V+ and V- to drive an RS-232 line. Short-circuit protected to GND (Ios ±60 mA typ). ESD-protected to ±15 kV HBM / IEC 61000-4-2 air discharge. |+| 15 | GND | power_in | Device ground reference for logic and analog supply return. |+| 16 | VCC | power_in | +3.0V to +5.5V single-supply input (absolute max +6V). Bypass to GND with a 1µF ceramic capacitor placed close to the pin. Typical supply current ICC = 0.3 mA (no load). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GATEMODE |+| Package | SSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `GM3232ENAENA`+- `GM3232ENAESA`+- `GM3232ENAETA`+- `GM3232ENAEBA`++## CAD (KiCad official)++- Symbol: `GM3232ENA`+- Footprint: `Package_SO:SSOP-16_5.3x6.2mm_P0.65mm`+- 3D model: SSOP-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [GATEMODE datasheet](docs/gm3232ena-datasheet.pdf) (13 pp, sha256 `d683feb35f456db6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
