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 boost charge-pump flying capacitor C1 (0.1 uF typ). Connect C1 between C1+ (pin 1) and C1- (pin 3). |+| 2 | V+ | power_out | Regulated +5.4V output from the internal boost charge pump. Bypass to GND with a 0.1 uF capacitor. |+| 3 | C1- | passive | Negative terminal of the boost charge-pump flying capacitor C1. Pair with C1+ (pin 1). |+| 4 | C2+ | passive | Positive terminal of the inverting charge-pump flying capacitor C2 (0.1 uF typ). Connect C2 between C2+ (pin 4) and C2- (pin 5). |+| 5 | C2- | passive | Negative terminal of the inverting charge-pump flying capacitor C2. Pair with C2+ (pin 4). |+| 6 | V- | power_out | Regulated -5.4V output from the internal inverting charge pump. Bypass to GND with a 0.1 uF capacitor. |+| 7 | T2OUT | output | RS-232 driver output of channel 2. Swings to approximately ±5V into a 3 kΩ / 1000 pF load; short-circuit current limited to ±60 mA. |+| 8 | R2IN | input | RS-232 receiver input of channel 2. Accepts ±20V input swing with 3-7 kΩ (5 kΩ typ) input resistance; thresholds VIL 0.8V / VIH 2.4V with 0.5V hysteresis. |+| 9 | R2OUT | output | TTL/CMOS receiver output of channel 2. VOL ≤ 0.4V at 1.6 mA sink; VOH ≥ VCC-0.6V at 1.0 mA source. |+| 10 | T2IN | input | TTL/CMOS driver input of channel 2. Thresholds VIL 0.8V / VIH 2.4V with 0.5V hysteresis; input leakage ±1 uA max. |+| 11 | T1IN | input | TTL/CMOS driver input of channel 1. Thresholds VIL 0.8V / VIH 2.4V with 0.5V hysteresis; input leakage ±1 uA max. |+| 12 | R1OUT | output | TTL/CMOS receiver output of channel 1. VOL ≤ 0.4V at 1.6 mA sink; VOH ≥ VCC-0.6V at 1.0 mA source. |+| 13 | R1IN | input | RS-232 receiver input of channel 1. Accepts ±20V input swing with 3-7 kΩ (5 kΩ typ) input resistance; thresholds VIL 0.8V / VIH 2.4V with 0.5V hysteresis. |+| 14 | T1OUT | output | RS-232 driver output of channel 1. Swings to approximately ±5V into a 3 kΩ / 1000 pF load; short-circuit current limited to ±60 mA. |+| 15 | GND | power_in | Ground reference for the device. |+| 16 | VCC | power_in | Positive supply input, +3.0V to +5.25V (recommended). Bypass with a 0.1 uF capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | GEC |+| Package | TSSOP-16 |+| Category | Interface |+| Pins | 16 |++## Ordering variants++- `WS3232ECY`+- `WS3232ECYWS3232ECN`+- `WS3232ECYWS3232ECA`++## CAD (KiCad official)++- Symbol: `WS3232ECY`+- 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:** [GEC datasheet](docs/ws3232ecy-datasheet.pdf) (10 pp, sha256 `f9cb4940c038f66c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
