MC14106BDR2G from onsemi, in a SOIC-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	1A	input	Schmitt trigger inverter #1 input. Positive-going threshold VT+ typically 2.9 V at VDD=5 V; negative-going threshold VT- typically 1.9 V. Input current ±0.1 uA max at VDD=15 V.
2	1Y	output	Schmitt trigger inverter #1 output (inverted from pin 1). Drives two low-power TTL loads or one LSTTL load over rated temperature. IOL 0.51 mA at VOL=0.4 V, VDD=5 V.
3	2A	input	Schmitt trigger inverter #2 input. Same electrical characteristics as inverter #1 input.
4	2Y	output	Schmitt trigger inverter #2 output (inverted from pin 3).
5	3A	input	Schmitt trigger inverter #3 input.
6	3Y	output	Schmitt trigger inverter #3 output (inverted from pin 5).
7	VSS	power_in	Negative supply / ground reference. All input and output voltages are referenced to VSS. Typically tied to 0 V.
8	4Y	output	Schmitt trigger inverter #4 output (inverted from pin 9).
9	4A	input	Schmitt trigger inverter #4 input.
10	5Y	output	Schmitt trigger inverter #5 output (inverted from pin 11).
11	5A	input	Schmitt trigger inverter #5 input.
12	6Y	output	Schmitt trigger inverter #6 output (inverted from pin 13).
13	6A	input	Schmitt trigger inverter #6 input.
14	VDD	power_in	Positive supply voltage. Operating range 3.0 V to 18 V DC, absolute maximum -0.5 V to +18.0 V. Bypass to VSS with a local decoupling capacitor.
