MC14584BDR2G from onsemi, in a SOIC-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	IN 1	input	Schmitt trigger input for channel 1. High-impedance CMOS input with double-diode protection, VT+ typ 2.7 V and VT- typ 2.1 V at VDD=5 V.
2	OUT 1	output	Inverted Schmitt trigger output for channel 1. Drives two low-power TTL loads or one low-power Schottky TTL load over rated temperature.
3	IN 2	input	Schmitt trigger input for channel 2. High-impedance CMOS input with double-diode protection.
4	OUT 2	output	Inverted Schmitt trigger output for channel 2.
5	IN 3	input	Schmitt trigger input for channel 3. High-impedance CMOS input with double-diode protection.
6	OUT 3	output	Inverted Schmitt trigger output for channel 3.
7	VSS	power_in	Negative supply / ground reference. Typically 0 V. All input/output voltages are referenced to VSS.
8	OUT 4	output	Inverted Schmitt trigger output for channel 4.
9	IN 4	input	Schmitt trigger input for channel 4. High-impedance CMOS input with double-diode protection.
10	OUT 5	output	Inverted Schmitt trigger output for channel 5.
11	IN 5	input	Schmitt trigger input for channel 5. High-impedance CMOS input with double-diode protection.
12	OUT 6	output	Inverted Schmitt trigger output for channel 6.
13	IN 6	input	Schmitt trigger input for channel 6. High-impedance CMOS input with double-diode protection.
14	VDD	power_in	Positive supply pin. Operating range 3.0 Vdc to 18 Vdc; absolute maximum -0.5 to +18.0 V referenced to VSS. Bypass with a local decoupling capacitor.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc14584bdr2g.step`	195 KB	You want the bare part, or you mark your own boards.
`mc14584bdr2g-etched.step`	2.9 MB	You want the part with `MC14584BDR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 711 faces against 237 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.
