MC74VHC1G14DFT1G from onsemi, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	NC	unconnected	No internal connection. Leave floating or tie to GND; do not use as a signal via.
2	A	input	Schmitt-trigger inverter input. CMOS thresholds (VT+ typ 3.0 V, VT- typ 2.3 V, hysteresis typ 0.67 V at VCC=4.5 V). Input is 5.5 V tolerant regardless of VCC.
3	GND	power_in	Ground reference (0 V). Bypass VCC to this pin with a local ceramic capacitor.
4	Y	output	Inverted push-pull CMOS output of the Schmitt trigger. Sources/sinks 8 mA at VCC=3.0 V (IOH/IOL rated ±25 mA absolute max). Y is 5.5 V over-voltage tolerant.
5	VCC	power_in	Positive supply rail, 2.0 V to 5.5 V recommended operating range (absolute max 7.0 V). ICC quiescent 1 µA typ at 5.5 V. Bypass to GND with a local ceramic capacitor.
