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 | VCC(A) | power_in | Supply voltage for port A and DIR reference. Operating range 1.2 V to 5.5 V (absolute max 6.5 V). |+| 2 | 1A | bidirectional | Channel 1 data I/O on the A-port side. Referenced to VCC(A). Direction (input vs output) is set by DIR: DIR=L makes 1A an input driven onto 1B; DIR=H makes 1A an output driven from 1B. |+| 3 | 2A | bidirectional | Channel 2 data I/O on the A-port side. Referenced to VCC(A). Direction is set by the shared DIR pin (DIR=L: 2A is input; DIR=H: 2A is output). |+| 4 | GND | power_in | Ground reference (0 V) for the device. |+| 5 | DIR | input | Direction control input, referenced to VCC(A). LOW selects A-to-B disabled/B-to-A transmission (nA=nB, nB is input); HIGH selects A-to-B transmission (nA input, nB=nA). Pulling either VCC(A) or VCC(B) to GND places both ports in high-impedance (suspend/OFF-state). |+| 6 | 2B | bidirectional | Channel 2 data I/O on the B-port side. Referenced to VCC(B). Direction opposite to 2A per the shared DIR pin (DIR=L: 2B is output; DIR=H: 2B is input). |+| 7 | 1B | bidirectional | Channel 1 data I/O on the B-port side. Referenced to VCC(B). Direction opposite to 1A per the shared DIR pin (DIR=L: 1B is output; DIR=H: 1B is input). |+| 8 | VCC(B) | power_in | Supply voltage for port B. Operating range 1.2 V to 5.5 V (absolute max 6.5 V). May be set independently of VCC(A) to translate between two voltage domains. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | VSSOP-8-0.5mm |+| Category | Logic |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `74LVC2T45DC-Q100H`+- `74LVCH2T45DC-Q100`+- `74LVC2T45GT-Q100`+- `74LVC2T45GS-Q100`++## CAD (KiCad official)++- Symbol: `74LVC2T45DC-Q100H`+- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`+- 3D model: VSSOP-8-0.5mm (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8588914232721625088) (30 pp, sha256 `19238362be695ea6`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
