**Texas Instruments** · Counters, Dividers · SOIC-16

CD4018BM96 from Texas Instruments, 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 | DATA | input | Data input to the first Johnson-counter stage; feeding back Q̄5..Q̄1 here sets divide-by-10, 8, 6, 4 or 2. |
| 2 | JAM 1 | input | Jam (preset) input for stage 1, loaded into the counter when PRESET ENABLE is high. |
| 3 | JAM 2 | input | Jam (preset) input for stage 2, loaded into the counter when PRESET ENABLE is high. |
| 4 | Q̄2 | output | Buffered inverted Q output of counter stage 2. |
| 5 | Q̄1 | output | Buffered inverted Q output of counter stage 1. |
| 6 | Q̄3 | output | Buffered inverted Q output of counter stage 3. |
| 7 | JAM 3 | input | Jam (preset) input for stage 3, loaded into the counter when PRESET ENABLE is high. |
| 8 | VSS | power_in | Ground / negative supply terminal; all voltages are referenced to VSS. |
| 9 | JAM 4 | input | Jam (preset) input for stage 4, loaded into the counter when PRESET ENABLE is high. |
| 10 | PRESET ENABLE | input | A high level allows the information on the JAM inputs to preset the counter. |
| 11 | Q̄4 | output | Buffered inverted Q output of counter stage 4. |
| 12 | JAM 5 | input | Jam (preset) input for stage 5, loaded into the counter when PRESET ENABLE is high. |
| 13 | Q̄5 | output | Buffered inverted Q output of counter stage 5. |
| 14 | CLOCK | input | Clock input with Schmitt-trigger action allowing unlimited rise and fall times; counter advances one count on the positive-going transition. |
| 15 | RESET | input | A high level clears the counter to an all-zero condition. |
| 16 | VDD | power_in | Positive supply; recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |
