74LVC125AS14-13 from Diodes Incorporated, in a SOP-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	1OE	input	Data enable input for buffer 1 (active low). When low, buffer 1 output 1Y follows input 1A; when high, 1Y is in high-impedance. Input voltage range 0-5.5 V.
2	1A	input	Data input for buffer 1. CMOS logic input, 5.5 V tolerant, VIH >= 0.65VCC, VIL <= 0.35VCC.
3	1Y	tri_state	Data output for buffer 1. 3-state CMOS output capable of sinking 24 mA at VCC = 3.3 V; enabled when 1OE is low.
4	2OE	input	Data enable input for buffer 2 (active low). When low, buffer 2 output 2Y follows input 2A; when high, 2Y is high-impedance.
5	2A	input	Data input for buffer 2. CMOS logic input, 5.5 V tolerant.
6	2Y	tri_state	Data output for buffer 2. 3-state CMOS output; enabled when 2OE is low.
7	GND	power_in	Ground reference. 0 V return for the device.
8	3Y	tri_state	Data output for buffer 3. 3-state CMOS output; enabled when 3OE is low.
9	3A	input	Data input for buffer 3. CMOS logic input, 5.5 V tolerant.
10	3OE	input	Data enable input for buffer 3 (active low). When low, buffer 3 output 3Y follows input 3A; when high, 3Y is high-impedance.
11	4Y	tri_state	Data output for buffer 4. 3-state CMOS output; enabled when 4OE is low.
12	4A	input	Data input for buffer 4. CMOS logic input, 5.5 V tolerant.
13	4OE	input	Data enable input for buffer 4 (active low). When low, buffer 4 output 4Y follows input 4A; when high, 4Y is high-impedance.
14	VCC	power_in	Positive supply voltage, 1.65 V to 5.5 V operating range (absolute max 6.5 V). Typical supply current ICC = 10 uA at VCC = 3.6 V.
