CD4020BPWR from Texas Instruments, in a TSSOP-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 | Q12 | output | Stage-12 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 2 | Q13 | output | Stage-13 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 3 | Q14 | output | Stage-14 (MSB) ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 4 | Q6 | output | Stage-6 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 5 | Q5 | output | Stage-5 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 6 | Q7 | output | Stage-7 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 7 | Q4 | output | Stage-4 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 8 | VSS | power_in | Negative power supply (ground) reference; 0 V in all operating conditions. |
| 9 | Q3 | output | Stage-3 (LSB available externally) ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 10 | Q9 | output | Stage-9 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 11 | Q10 | output | Stage-10 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 12 | Q11 | output | Stage-11 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 13 | Q8 | output | Stage-8 ripple-carry counter output; valid for VDD = 3 V to 18 V. |
| 14 | RESET | input | Active-high asynchronous master reset; sets all counter stages to 0 when HIGH. |
| 15 | CP | input | Clock input; counter advances on the falling (negative) edge of each pulse; input frequency up to 12 MHz at VDD = 10 V. |
| 16 | VDD | power_in | Positive power supply; operating range 3 V to 18 V, absolute maximum −0.5 V to +20 V. |
