SN74LVC3G34DCTR from Texas Instruments, in a MSOP-8-2.8mm. 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 | 1A | input | Buffer 1 input. CMOS logic input; accepts up to 5.5 V regardless of VCC (down-translation supported). |
| 7 | 1Y | output | Buffer 1 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V. |
| 3 | 2A | input | Buffer 2 input. CMOS logic input; accepts up to 5.5 V regardless of VCC. |
| 5 | 2Y | output | Buffer 2 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V. |
| 6 | 3A | input | Buffer 3 input. CMOS logic input; accepts up to 5.5 V regardless of VCC. |
| 2 | 3Y | output | Buffer 3 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V. |
| 4 | GND | power_in | Device ground reference. Connect to system 0 V. |
| 8 | VCC | power_in | Positive supply, 1.65 V to 5.5 V operating (1.5 V data-retention minimum). Decouple locally to GND with a 0.1 µF ceramic. |
