CD4028BE from Texas Instruments, in a DIP-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 | Buffered decoded output 4, goes high when the BCD input code equals 4. |
| 2 | 2 | output | Buffered decoded output 2, goes high when the BCD input code equals 2. |
| 3 | 0 | output | Buffered decoded output 0, goes high when the BCD input code equals 0. |
| 4 | 7 | output | Buffered decoded output 7, goes high when the BCD input code equals 7. |
| 5 | 9 | output | Buffered decoded output 9, goes high when the BCD input code equals 9 (low in octal mode). |
| 6 | 5 | output | Buffered decoded output 5, goes high when the BCD input code equals 5. |
| 7 | 6 | output | Buffered decoded output 6, goes high when the BCD input code equals 6. |
| 8 | VSS | power_in | Ground supply terminal (VSS), 0 V reference for VDD of 3 V to 18 V. |
| 9 | 8 | output | Buffered decoded output 8, goes high when the BCD input code equals 8 (low in octal mode). |
| 10 | A | input | BCD input A (least significant bit), CMOS-protected input limited to -0.5 V to VDD+0.5 V. |
| 11 | D | input | BCD input D (most significant bit); D = 0 selects binary-to-octal decoding on A to C. |
| 12 | C | input | BCD input C, CMOS-protected input limited to -0.5 V to VDD+0.5 V. |
| 13 | B | input | BCD input B, CMOS-protected input limited to -0.5 V to VDD+0.5 V. |
| 14 | 1 | output | Buffered decoded output 1, goes high when the BCD input code equals 1. |
| 15 | 3 | output | Buffered decoded output 3, goes high when the BCD input code equals 3. |
| 16 | VDD | power_in | Positive supply voltage, recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V. |
