74HC175D from Nexperia, 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	MR	input	Asynchronous master reset input, active LOW. Driving MR LOW forces all four Q outputs LOW and all Q-bar outputs HIGH independently of the clock.
2	Q0	output	True (non-inverting) flip-flop output for channel 0. Reflects the stored D0 value after a LOW-to-HIGH CP edge.
3	Q0_N	output	Complementary (inverted) flip-flop output for channel 0.
4	D0	input	Data input for flip-flop 0. Sampled on the LOW-to-HIGH transition of CP subject to setup/hold timing.
5	D1	input	Data input for flip-flop 1. Sampled on the LOW-to-HIGH transition of CP.
6	Q1_N	output	Complementary (inverted) flip-flop output for channel 1.
7	Q1	output	True (non-inverting) flip-flop output for channel 1.
8	GND	power_in	Ground reference (0 V).
9	CP	input	Common clock input, positive-edge triggered. All four flip-flops latch their D inputs on the LOW-to-HIGH transition.
10	Q2	output	True (non-inverting) flip-flop output for channel 2.
11	Q2_N	output	Complementary (inverted) flip-flop output for channel 2.
12	D2	input	Data input for flip-flop 2. Sampled on the LOW-to-HIGH transition of CP.
13	D3	input	Data input for flip-flop 3. Sampled on the LOW-to-HIGH transition of CP.
14	Q3_N	output	Complementary (inverted) flip-flop output for channel 3.
15	Q3	output	True (non-inverting) flip-flop output for channel 3.
16	VCC	power_in	Positive supply voltage. 2.0 V to 6.0 V for 74HC175; 4.5 V to 5.5 V for 74HCT175.
