SN74LVC1G02DB from lingxingic, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B | input | Data input B of the 2-input NOR gate (Y = NOT(A OR B)); the datasheet gives a recommended input voltage range of 0 V to 5.5 V. |
| 2 | A | input | Data input A of the 2-input NOR gate (Y = NOT(A OR B)); the datasheet gives a recommended input voltage range of 0 V to 5.5 V. |
| 3 | GND | power_in | Ground (0 V) reference for the device. |
| 4 | Y | output | NOR gate data output; the datasheet specifies ±24 mA output drive at VCC = 3.0 V. |
| 5 | VCC | power_in | Supply voltage; the recommended operating range is 1.65 V to 5.5 V. |
