SN74ACT14PWR from Texas Instruments, 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	Channel 1 Schmitt-trigger input A. TTL-compatible input with hysteresis (VT+ typ 1.7 V, VT- typ 1.0 V at VCC=5.5 V). Tolerant to 5.5 V regardless of VCC.
2	1Y	output	Channel 1 inverted output (Y = /A). Balanced CMOS push-pull output; drive ±24 mA at VCC=4.5 V.
3	2A	input	Channel 2 Schmitt-trigger input A. TTL-compatible input with hysteresis.
4	2Y	output	Channel 2 inverted output (Y = /A). Balanced CMOS push-pull output.
5	3A	input	Channel 3 Schmitt-trigger input A. TTL-compatible input with hysteresis.
6	3Y	output	Channel 3 inverted output (Y = /A). Balanced CMOS push-pull output.
7	GND	power_in	Ground return (0 V). Reference for all logic levels and supply currents.
8	4Y	output	Channel 4 inverted output (Y = /A). Balanced CMOS push-pull output.
9	4A	input	Channel 4 Schmitt-trigger input A. TTL-compatible input with hysteresis.
10	5Y	output	Channel 5 inverted output (Y = /A). Balanced CMOS push-pull output.
11	5A	input	Channel 5 Schmitt-trigger input A. TTL-compatible input with hysteresis.
12	6Y	output	Channel 6 inverted output (Y = /A). Balanced CMOS push-pull output.
13	6A	input	Channel 6 Schmitt-trigger input A. TTL-compatible input with hysteresis.
14	VCC	power_in	Positive supply. Operating range 4.5 V to 5.5 V. Bypass to GND with a 0.1 µF ceramic capacitor near the pin.
