CD4028BM from HGSEMI, in a SOIC-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 | 4 | output | Decoded output 4, high when BCD input equals 4. |
| 2 | 2 | output | Decoded output 2, high when BCD input equals 2. |
| 3 | 0 | output | Decoded output 0, high when BCD input equals 0. |
| 4 | 7 | output | Decoded output 7, high when input equals 7 and forced low when D is high. |
| 5 | 9 | output | Decoded output 9, high when BCD input equals 9. |
| 6 | 5 | output | Decoded output 5, high when BCD input equals 5. |
| 7 | 6 | output | Decoded output 6, high when BCD input equals 6. |
| 8 | VSS | power_in | Ground supply pin, VSS = 0V. |
| 9 | 8 | output | Decoded output 8, high when BCD input equals 8. |
| 10 | A | input | BCD address input A (least significant bit), diode-clamped to VDD and VSS, input range 0 to VDD. |
| 11 | D | input | BCD address input D (most significant bit); a high level inhibits octal decoding and forces outputs 0-7 low. |
| 12 | C | input | BCD address input C, diode-clamped to VDD and VSS, input range 0 to VDD. |
| 13 | B | input | BCD address input B, diode-clamped to VDD and VSS, input range 0 to VDD. |
| 14 | 1 | output | Decoded output 1, high when BCD input equals 1. |
| 15 | 3 | output | Decoded output 3, high when BCD input equals 3. |
| 16 | VDD | power_in | Positive supply pin, recommended 3V to 15V, absolute maximum 18V. |
