SN74HC365DR from Texas Instruments, in a SOIC-16. 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	OE1	input	Active-low output-enable 1. When OE1 is low AND OE2 is low, all six Y outputs follow their A inputs. When OE1 is high, all outputs go to the high-impedance (3-state) state regardless of OE2.
2	A1	input	Data input for buffer channel 1. Non-inverted; drives Y1 when both OE inputs are low.
3	Y1	tri_state	3-state buffered output for channel 1. Follows A1 when both OE pins are low; high-impedance otherwise. ±6-mA drive at VCC = 5 V.
4	A2	input	Data input for buffer channel 2. Non-inverted; drives Y2 when both OE inputs are low.
5	Y2	tri_state	3-state buffered output for channel 2. Follows A2 when both OE pins are low; high-impedance otherwise.
6	A3	input	Data input for buffer channel 3. Non-inverted; drives Y3 when both OE inputs are low.
7	Y3	tri_state	3-state buffered output for channel 3. Follows A3 when both OE pins are low; high-impedance otherwise.
8	GND	power_in	Ground reference (0 V). All logic thresholds and output-low levels are referenced to this pin.
9	Y4	tri_state	3-state buffered output for channel 4. Follows A4 when both OE pins are low; high-impedance otherwise.
10	A4	input	Data input for buffer channel 4. Non-inverted; drives Y4 when both OE inputs are low.
11	Y5	tri_state	3-state buffered output for channel 5. Follows A5 when both OE pins are low; high-impedance otherwise.
12	A5	input	Data input for buffer channel 5. Non-inverted; drives Y5 when both OE inputs are low.
13	Y6	tri_state	3-state buffered output for channel 6. Follows A6 when both OE pins are low; high-impedance otherwise.
14	A6	input	Data input for buffer channel 6. Non-inverted; drives Y6 when both OE inputs are low.
15	OE2	input	Active-low output-enable 2. When OE1 is low AND OE2 is low, all six Y outputs follow their A inputs. When OE2 is high, all outputs go to the high-impedance (3-state) state regardless of OE1.
16	VCC	power_in	Positive supply voltage. Recommended operating range 2 V to 6 V (nom 5 V). Decouple with a 0.1-µF (and optionally a parallel 1-µF) bypass capacitor placed as close to the pin as possible.
