**Slkor SLKORMICRO Elec** · Flip Flops · SOP-14

CD4013 from Slkor SLKORMICRO Elec, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1Q | output | Flip-flop 1 non-inverting logic output. CMOS push-pull output; drives typ. 1 mA at VDD=5 V. |
| 2 | 1Q_N | output | Flip-flop 1 inverting logic output (complement of 1Q). CMOS push-pull output. |
| 3 | 1CP | input | Flip-flop 1 clock input. Low-to-high (rising) edge triggers data transfer from 1D to 1Q. Max fCL 7 MHz @ VDD=5 V typ. |
| 4 | 1CD | input | Flip-flop 1 asynchronous reset (clear) input, active-high. Independent of clock; forces 1Q low, 1Q_N high. |
| 5 | 1D | input | Flip-flop 1 data input. Logic level sampled on the rising edge of 1CP is transferred to 1Q. |
| 6 | 1SD | input | Flip-flop 1 asynchronous set input, active-high. Independent of clock; forces 1Q high, 1Q_N low. |
| 7 | VSS | power_in | Negative supply / system ground (0 V). |
| 8 | 2SD | input | Flip-flop 2 asynchronous set input, active-high. Independent of clock; forces 2Q high, 2Q_N low. |
| 9 | 2D | input | Flip-flop 2 data input. Logic level sampled on the rising edge of 2CP is transferred to 2Q. |
| 10 | 2CD | input | Flip-flop 2 asynchronous reset (clear) input, active-high. Independent of clock; forces 2Q low, 2Q_N high. |
| 11 | 2CP | input | Flip-flop 2 clock input. Low-to-high (rising) edge triggers data transfer from 2D to 2Q. |
| 12 | 2Q_N | output | Flip-flop 2 inverting logic output (complement of 2Q). CMOS push-pull output. |
| 13 | 2Q | output | Flip-flop 2 non-inverting logic output. CMOS push-pull output. |
| 14 | VDD | power_in | Positive supply. Recommended operating range 3 V to 15 V; absolute maximum 15 V (from GND=VSS). |
