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 | 1OE | input | Output enable for switch channel 1, active high. When high, the FET switch between 1A and 1B is closed; when low, the switch is open (high impedance). VIH ≥ 2 V (VCC = 2.7-3.6 V). |+| 2 | 1A | bidirectional | Channel 1 A-side switch terminal. Bidirectional data I/O; connects to 1B when 1OE is high. Rail-to-rail signal swing supported; ~5 Ω on-resistance. |+| 3 | 1B | bidirectional | Channel 1 B-side switch terminal. Bidirectional data I/O; connects to 1A when 1OE is high. |+| 4 | 2OE | input | Output enable for switch channel 2, active high. Closes the FET between 2A and 2B when high. |+| 5 | 2A | bidirectional | Channel 2 A-side switch terminal. Bidirectional data I/O; connects to 2B when 2OE is high. |+| 6 | 2B | bidirectional | Channel 2 B-side switch terminal. Bidirectional data I/O; connects to 2A when 2OE is high. |+| 7 | GND | power_in | Ground reference for the device. |+| 8 | 3B | bidirectional | Channel 3 B-side switch terminal. Bidirectional data I/O; connects to 3A when 3OE is high. |+| 9 | 3A | bidirectional | Channel 3 A-side switch terminal. Bidirectional data I/O; connects to 3B when 3OE is high. |+| 10 | 3OE | input | Output enable for switch channel 3, active high. Closes the FET between 3A and 3B when high. |+| 11 | 4B | bidirectional | Channel 4 B-side switch terminal. Bidirectional data I/O; connects to 4A when 4OE is high. |+| 12 | 4A | bidirectional | Channel 4 A-side switch terminal. Bidirectional data I/O; connects to 4B when 4OE is high. |+| 13 | 4OE | input | Output enable for switch channel 4, active high. Closes the FET between 4A and 4B when high. |+| 14 | VCC | power_in | Positive supply. Recommended VCC = 2.3 V to 3.6 V; absolute maximum 4.6 V. Decouple locally with a bypass capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++- `SN74CBTLV3126PWRPW`+- `SN74CBTLV3126PWRPWR`+- `SN74CBTLV3126PWRD`+- `SN74CBTLV3126PWRDGV`+- `SN74CBTLV3126PWRRGY`+- `SN74CBTLV3126PWRBQA`+- `SN74CBTLV3126PWRDYY`+- `SN74CBTLV3126PWRDBQ`++## CAD (KiCad official)++- Symbol: `SN74CBTLV3126PWR`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn74cbtlv3126.pdf) (37 pp, sha256 `65fbc35c107d5ea2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
