CD74HC4050NSR from Texas Instruments, in a SO-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in Supply voltage, 2V to 6V for HC types (absolute max -0.5V to 7V).
2 1Y output Buffer 1 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
3 1A input Buffer 1 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
4 2Y output Buffer 2 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
5 2A input Buffer 2 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
6 3Y output Buffer 3 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
7 3A input Buffer 3 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
8 GND power_in Ground (0V) reference.
9 4A input Buffer 4 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
10 4Y output Buffer 4 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
11 5A input Buffer 5 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
12 5Y output Buffer 5 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
13 NC unconnected No internal connection.
14 6A input Buffer 6 input, accepts levels up to 15V (VI range 0V to 15V) for high-to-low level translation.
15 6Y output Buffer 6 non-inverting output (HC4050), swings 0V to VCC with standard 10 LSTTL load fanout.
