U74LVC2G17G

UTC Unisonic Tech · Logic Gates · SOT-363

U74LVC2G17G from UTC Unisonic Tech, in a SOT-363. 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 1A input Schmitt-trigger input of buffer 1; 5 V tolerant (input range 0 to 5.5 V), and unused inputs must be held at VCC or GND.
2 GND power_in Ground (0 V) reference for the device.
3 2A input Schmitt-trigger input of buffer 2; 5 V tolerant (input range 0 to 5.5 V), and unused inputs must be held at VCC or GND.
4 2Y output Buffer 2 output that follows 2A, with ±24 mA drive at VCC = 3.3 V.
5 VCC power_in Supply voltage, operating range 1.65 V to 5.5 V (absolute maximum 6.5 V).
6 1Y output Buffer 1 output that follows 1A, with ±24 mA drive at VCC = 3.3 V.
