# CD4024BPWR

**Texas Instruments** · Counters, Dividers · TSSOP-14

CD4024BPWR from Texas Instruments, in a TSSOP-14. 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 | φ | input | Counter clock input (Schmitt-trigger, unlimited rise/fall time) on which the counter advances one count on each negative transition. |
| 2 | RESET | input | Common reset input; a high level resets the counter to its all-zeros state. |
| 3 | Q7 | output | Buffered output of counter stage 7. |
| 4 | Q6 | output | Buffered output of counter stage 6. |
| 5 | Q5 | output | Buffered output of counter stage 5. |
| 6 | Q4 | output | Buffered output of counter stage 4. |
| 7 | VSS | power_in | Ground (negative supply) terminal; all voltages are referenced to VSS. |
| 8 | NC | unconnected | No connection. |
| 9 | Q3 | output | Buffered output of counter stage 3. |
| 10 | NC | unconnected | No connection. |
| 11 | Q2 | output | Buffered output of counter stage 2. |
| 12 | Q1 | output | Buffered output of counter stage 1. |
| 13 | NC | unconnected | No connection. |
| 14 | VDD | power_in | Positive supply voltage, recommended 3 V to 18 V, absolute maximum -0.5 V to +20 V referenced to VSS. |

## CAD (KiCad official)

- Symbol: `CD4024BPWR`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `cd4024bpwr-etched.step` / `cd4024bpwr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cd4024bpwr.step` / `cd4024bpwr.glb` are the bare package body.
