SN74LVC1G02DB

lingxingic · Logic Gates · SOT-23-5

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.
