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 | VCC | power_in | Input-side supply. Sets the input signal thresholds (TTL or CMOS reference). Operating range 3 to 18 Vdc; absolute max -0.5 to +18 V referenced to VSS. |+| 2 | Aout | output | Level-shifted non-inverting output for channel A. Output swing is VSS to VDD; drive capable of two low-power TTL loads or one LS-TTL load. |+| 3 | Ain | input | Channel A input. Threshold referenced to VCC (TTL or CMOS depending on MODE). Diode protected to VSS; input must remain within VSS to VDD range. |+| 4 | Bout | output | Level-shifted non-inverting output for channel B. Output swing VSS to VDD. |+| 5 | Bin | input | Channel B input. Threshold set by VCC and MODE selection. Diode protected to VSS. |+| 6 | Cout | output | Level-shifted non-inverting output for channel C. Output swing VSS to VDD. |+| 7 | Cin | input | Channel C input. Threshold set by VCC and MODE selection. Diode protected to VSS. |+| 8 | VSS | power_in | Negative supply / ground reference for the device. All other voltages are referenced to VSS. |+| 9 | Din | input | Channel D input. Threshold set by VCC and MODE selection. Diode protected to VSS. |+| 10 | Dout | output | Level-shifted non-inverting output for channel D. Output swing VSS to VDD. |+| 11 | Ein | input | Channel E input. Threshold set by VCC and MODE selection. Diode protected to VSS. |+| 12 | Eout | output | Level-shifted non-inverting output for channel E. Output swing VSS to VDD. |+| 13 | MODE | input | TTL/CMOS mode select. MODE = 1 (VCC) selects TTL input logic levels; MODE = 0 (VSS) selects CMOS input logic levels. Output is always CMOS levels referenced to VDD. |+| 14 | Fin | input | Channel F input. Threshold set by VCC and MODE selection. Diode protected to VSS. |+| 15 | Fout | output | Level-shifted non-inverting output for channel F. Output swing VSS to VDD. |+| 16 | VDD | power_in | Output-side supply. Sets the CMOS output voltage swing. Operating range 3 to 18 Vdc; absolute max -0.5 to +18 V referenced to VSS. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SOIC-16 |+| Category | Logic |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `MC14504BDR2GDG`+- `MC14504BDR2G`+- `MC14504BDR2GDTG`+- `MC14504BDR2GDTR2G`+- `MC14504BDR2GFELG`++## CAD (KiCad official)++- Symbol: `MC14504BDR2G`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/mc14504b-d.pdf) (7 pp, sha256 `8768b6ddaea7ffd1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
