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 | Channel-1 active-low output enable. When 1OE is low, buffer 1's output (1Y) is driven from 1A; when 1OE is high, 1Y is placed in the high-impedance (3-state) condition. CMOS-compatible input tolerant to 5.5 V. |+| 2 | 1A | input | Channel-1 buffer data input. Its logic level is passed to output 1Y when 1OE is asserted low. CMOS-compatible input, 5.5-V tolerant regardless of VCC. |+| 3 | 2Y | tri_state | Channel-2 buffer 3-state output. Drives the logic level of 2A when 2OE is low; goes to high-impedance when 2OE is high. ±24-mA drive at VCC = 3.3 V. |+| 4 | GND | power_in | Device ground reference (0 V). Must be the common return for VCC bypass and all logic signals. |+| 5 | 2A | input | Channel-2 buffer data input. Its logic level is passed to output 2Y when 2OE is asserted low. CMOS-compatible input, 5.5-V tolerant regardless of VCC. |+| 6 | 1Y | tri_state | Channel-1 buffer 3-state output. Drives the logic level of 1A when 1OE is low; goes to high-impedance when 1OE is high. ±24-mA drive at VCC = 3.3 V. |+| 7 | 2OE | input | Channel-2 active-low output enable. When 2OE is low, buffer 2's output (2Y) is driven from 2A; when 2OE is high, 2Y is placed in the high-impedance (3-state) condition. CMOS-compatible input tolerant to 5.5 V. |+| 8 | VCC | power_in | Positive supply rail, 1.65 V to 3.6 V recommended (5-V VCC operation also supported per Features). Decouple with a 0.1-µF ceramic capacitor to GND close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | MSOP-8 |+| Category | Logic |+| Pins | 8 |++## Ordering variants++- `SN74LVC2G126DCTR`+- `SN74LVC2G126DCTRDCUR`+- `SN74LVC2G126DCTRDCU`+- `SN74LVC2G126DCTRYZPR`+- `SN74LVC2G126DCTRYZP`++## CAD (KiCad official)++- Symbol: `SN74LVC2G126DCTR`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (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/sn74lvc2g126dctr.pdf) (None pp, sha256 `7cef06148d6338b5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
