74VHC14FT from TOSHIBA 74VHC14FT, 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	1A	input	Schmitt-trigger input of inverter 1. Input voltage range 0 to 5.5 V (independent of Vcc). Typical Vp = 3.15 V, Vn = 1.35 V, VH = 0.4 V at Vcc = 4.5 V.
2	1Y	output	Inverted CMOS output of Schmitt inverter 1. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
3	2A	input	Schmitt-trigger input of inverter 2. Input voltage range 0 to 5.5 V.
4	2Y	output	Inverted CMOS output of Schmitt inverter 2. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
5	3A	input	Schmitt-trigger input of inverter 3. Input voltage range 0 to 5.5 V.
6	3Y	output	Inverted CMOS output of Schmitt inverter 3. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
7	GND	power_in	Ground reference (0 V). Connect to system ground.
8	4Y	output	Inverted CMOS output of Schmitt inverter 4. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
9	4A	input	Schmitt-trigger input of inverter 4. Input voltage range 0 to 5.5 V.
10	5Y	output	Inverted CMOS output of Schmitt inverter 5. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
11	5A	input	Schmitt-trigger input of inverter 5. Input voltage range 0 to 5.5 V.
12	6Y	output	Inverted CMOS output of Schmitt inverter 6. Drive capability Ioh/Iol = ±8 mA at Vcc = 4.5 V.
13	6A	input	Schmitt-trigger input of inverter 6. Input voltage range 0 to 5.5 V.
14	VCC	power_in	Positive supply voltage. Operating range 2.0 to 5.5 V (absolute max 7.0 V). Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.
