lingxingic · Inverters · SOT-353

SN74LVC1G14DC from lingxingic, 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 n.c. unconnected Not connected (不连接); the datasheet gives no internal connection for this pin.
2 A input Data input; recommended input voltage is 0 V to 5.5 V, and the absolute maximum input voltage is -0.5 V to +6.5 V.
3 GND power_in Ground (0 V) reference for the device.
4 Y output Data output (inverting Schmitt-trigger output, Y = NOT A); output current is limited to ±50 mA absolute maximum, and in operating mode the output voltage must stay between 0 V and VCC.
5 VCC power_in Supply voltage; recommended range is 1.65 V to 5.5 V, with an absolute maximum of -0.5 V to +6.5 V.
