74HC76S from GR, in a SOP-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	1CK	input	Clock input for flip-flop 1 (active on falling edge). Schmitt-compatible CMOS input; VIH >= 0.7VCC, VIL <= 0.3VCC (approx).
2	1PR	input	Preset input for flip-flop 1, active LOW. Asynchronously forces 1Q HIGH / 1Q-bar LOW.
3	1CLR	input	Clear input for flip-flop 1, active LOW. Asynchronously forces 1Q LOW / 1Q-bar HIGH.
4	1J	input	J data input for flip-flop 1. Sampled on the falling edge of 1CK together with 1K to determine next-state behaviour (hold/set/reset/toggle).
5	VCC	power_in	Positive supply, 2.0 V to 6.0 V (5 V typical). Absolute maximum -0.5 V to 6.5 V.
6	2CK	input	Clock input for flip-flop 2 (active on falling edge).
7	2PR	input	Preset input for flip-flop 2, active LOW. Asynchronously forces 2Q HIGH / 2Q-bar LOW.
8	2CLR	input	Clear input for flip-flop 2, active LOW. Asynchronously forces 2Q LOW / 2Q-bar HIGH.
9	2J	input	J data input for flip-flop 2. Sampled on the falling edge of 2CK together with 2K.
10	2Q_N	output	Inverted Q output for flip-flop 2. Push-pull CMOS output; can drive up to 10 LSTTL loads (approx. 4 mA at VCC=4.5 V).
11	2Q	output	Non-inverted Q output for flip-flop 2. Push-pull CMOS; drives up to 10 LSTTL loads.
12	2K	input	K data input for flip-flop 2. Sampled on the falling edge of 2CK together with 2J.
13	GND	power_in	Ground (0 V) reference for supply and I/O.
14	1Q_N	output	Inverted Q output for flip-flop 1. Push-pull CMOS; drives up to 10 LSTTL loads.
15	1Q	output	Non-inverted Q output for flip-flop 1. Push-pull CMOS; drives up to 10 LSTTL loads.
16	1K	input	K data input for flip-flop 1. Sampled on the falling edge of 1CK together with 1J.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74hc76s.step`	217 KB	You want the bare part, or you mark your own boards.
`74hc76s-etched.step`	1.9 MB	You want the part with `74HC76S` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 480 faces against 267 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
