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 | NC | unconnected | No Connect. On CAT24C16 all three device-address inputs (A0/A1/A2) are used internally as address bits a8/a9/a10, so this pin is unused. |+| 2 | NC | unconnected | No Connect on CAT24C16; the A1 address-select input is used as an internal address bit for the 16-Kb variant. |+| 3 | NC | unconnected | No Connect on CAT24C16; the A2 address-select input is used as an internal address bit for the 16-Kb variant. |+| 4 | VSS | power_in | Ground reference (0 V) for the device. |+| 5 | SDA | bidirectional | Serial Data I/O for the I2C bus. Open-drain output; requires an external pull-up to VCC. Data is clocked in on the rising edge of SCL and shifted out on the falling edge. Schmitt-trigger input with noise suppression; input capacitance 8 pF max. |+| 6 | SCL | input | Serial Clock input for the I2C bus, driven by the master. Supports Standard (100 kHz) and Fast (400 kHz) modes. Schmitt-trigger input with noise suppression. |+| 7 | WP | input | Write Protect input. When held HIGH, all write operations to the entire memory array are inhibited; when LOW (or left floating; internally pulled LOW), writes are allowed. WP input current 130 uA max at VCC = 5.5 V. |+| 8 | VCC | power_in | Supply voltage, 1.7 V to 5.5 V. Read current 1 mA typ, write current 2 mA typ at 400 kHz; standby current 1 uA max (industrial, VCC <= 3.3 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `CAT24C16WI-GT3WI-GT3`+- `CAT24C16WI-GT3WI`+- `CAT24C16WI-GT3LI`+- `CAT24C16WI-GT3YI`+- `CAT24C16WI-GT3ZI`+- `CAT24C16WI-GT3USI`+- `CAT24C16WI-GT3VP2I`+- `CAT24C16WI-GT3HU4I`+- `CAT24C16WI-GT3TDI`+- `CAT24C16WI-GT3C5AI`+- `CAT24C16WI-GT3C4AI`+- `CAT24C16WI-GT3C4UI`++## CAD (KiCad official)++- Symbol: `CAT24C16WI-GT3`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/cat24c16wi-gt3-d.pdf) (23 pp, sha256 `1068a4f09584c5b3`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
