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 | INT | output | Active-LOW open-drain interrupt output. Asserted when any input pin state differs from its corresponding Input Port register value. Requires an external pull-up resistor to Vcc; IOL = 3 mA at VOL = 0.4 V. |+| 2 | A1 | input | Hardware I2C slave-address select bit 1. Must be tied directly to Vcc or GND (never floating) and must not change while device is powered. Sets bit 2 of the 7-bit slave address (base 0x20). |+| 3 | A2 | input | Hardware I2C slave-address select bit 2. Must be tied directly to Vcc or GND (never floating). Sets bit 3 of the 7-bit slave address (base 0x20). |+| 4 | P00 | bidirectional | Port 0 bit 0. Push-pull GPIO, configured as input at power-on. Per-I/O limit 25 mA; VIH = 0.7xVcc, VIL = 0.3xVcc; IOL up to 25 mA, IOH up to -10 mA. |+| 5 | P01 | bidirectional | Port 0 bit 1. Push-pull GPIO, configured as input at power-on. Same drive limits as P00. |+| 6 | P02 | bidirectional | Port 0 bit 2. Push-pull GPIO, configured as input at power-on. |+| 7 | P03 | bidirectional | Port 0 bit 3. Push-pull GPIO, configured as input at power-on. |+| 8 | P04 | bidirectional | Port 0 bit 4. Push-pull GPIO, configured as input at power-on. |+| 9 | P05 | bidirectional | Port 0 bit 5. Push-pull GPIO, configured as input at power-on. |+| 10 | P06 | bidirectional | Port 0 bit 6. Push-pull GPIO, configured as input at power-on. |+| 11 | P07 | bidirectional | Port 0 bit 7. Push-pull GPIO, configured as input at power-on. Total sourced current on P07-P00 must be limited to 80 mA. |+| 12 | GND | power_in | Supply ground (0 V reference). |+| 13 | P10 | bidirectional | Port 1 bit 0. Push-pull GPIO, configured as input at power-on. |+| 14 | P11 | bidirectional | Port 1 bit 1. Push-pull GPIO, configured as input at power-on. |+| 15 | P12 | bidirectional | Port 1 bit 2. Push-pull GPIO, configured as input at power-on. |+| 16 | P13 | bidirectional | Port 1 bit 3. Push-pull GPIO, configured as input at power-on. |+| 17 | P14 | bidirectional | Port 1 bit 4. Push-pull GPIO, configured as input at power-on. |+| 18 | P15 | bidirectional | Port 1 bit 5. Push-pull GPIO, configured as input at power-on. |+| 19 | P16 | bidirectional | Port 1 bit 6. Push-pull GPIO, configured as input at power-on. |+| 20 | P17 | bidirectional | Port 1 bit 7. Push-pull GPIO, configured as input at power-on. Total sourced current on P17-P10 must be limited to 80 mA. |+| 21 | A0 | input | Hardware I2C slave-address select bit 0. Must be tied directly to Vcc or GND (never floating). Sets bit 1 of the 7-bit slave address (base 0x20, giving 0x20..0x27). |+| 22 | SCL | input | I2C-bus serial clock input. Requires external pull-up to Vcc. Supports standard-mode (100 kHz) and fast-mode (400 kHz); VIH = 0.7xVcc, VIL = 0.3xVcc, 5 V tolerant. |+| 23 | SDA | bidirectional | I2C-bus serial data line (open-drain). Requires external pull-up to Vcc. IOL >= 3 mA at VOL = 0.4 V; 5 V tolerant. |+| 24 | VCC | power_in | Positive supply voltage, 2.3 V to 5.5 V. Typical ICC = 135 uA (max 200 uA) at 5.5 V with fSCL = 100 kHz; standby current typ 0.25 uA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XINLUDA |+| Package | TSSOP-24 |+| Category | Interface |+| Pins | 24 |++## Ordering variants++- `XL9535D`+- `XL9535XL9555D`+- `XL9535SS`+- `XL9535XL9555SS`+- `XL9535`+- `XL9535XL9555`+- `XL9535QF24`+- `XL9535XL9555QF24`++## CAD (KiCad official)++- Symbol: `XL9535`+- Footprint: `Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm`+- 3D model: TSSOP-24 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XINLUDA datasheet](docs/xl9535-datasheet.pdf) (25 pp, sha256 `80ea36f92c4bf704`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
