MC74HC14ADTR2G from onsemi, in a TSSOP-14. 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	A1	input	Schmitt-trigger inverter 1 input. Typical hysteresis 1.65 V at VCC=4.5 V. Input leakage 0.1 uA max.
2	Y1	output	Schmitt-trigger inverter 1 output (Y1 = /A1). Drives up to 10 LSTTL loads; VOH >= 3.98 V, VOL <= 0.26 V at VCC=4.5 V, Iout=4.0 mA.
3	A2	input	Schmitt-trigger inverter 2 input. Same characteristics as A1.
4	Y2	output	Schmitt-trigger inverter 2 output (Y2 = /A2).
5	A3	input	Schmitt-trigger inverter 3 input.
6	Y3	output	Schmitt-trigger inverter 3 output (Y3 = /A3).
7	GND	power_in	Ground reference (0 V). Common return for VCC and all signals.
8	Y4	output	Schmitt-trigger inverter 4 output (Y4 = /A4).
9	A4	input	Schmitt-trigger inverter 4 input.
10	Y5	output	Schmitt-trigger inverter 5 output (Y5 = /A5).
11	A5	input	Schmitt-trigger inverter 5 input.
12	Y6	output	Schmitt-trigger inverter 6 output (Y6 = /A6).
13	A6	input	Schmitt-trigger inverter 6 input.
14	VCC	power_in	Positive supply voltage, 2.0 to 6.0 V operating range (absolute max -0.5 to +7.0 V). Quiescent supply current ICC <= 1.0 uA at 25 C.
