UTC Unisonic Tech · Logic Gates · SOT-353

U74LVC1G04G-AL5-R from UTC Unisonic Tech, in a SOT-353. 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 NC unconnected Not connected; the datasheet pin configuration marks this pin NC and states no function for it.
2 A input Logic input of the single inverter (Y = A); recommended input voltage range is 0 to 5.5 V.
3 GND power_in Ground reference pin for the device.
4 Y output Inverted logic output; recommended output voltage range is 0 to VCC, with ±24 mA drive at VCC = 3.3 V.
5 VCC power_in Supply pin; operating supply range is 1.65 V to 5.5 V, with data retention only down to 1.5 V.
