CD4026BE from Texas Instruments, in a DIP-16. 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 | CLOCK | input | Schmitt-triggered clock input; the decade counter advances one count on the positive-going clock transition when CLOCK INHIBIT is low. |
| 2 | CLOCK INHIBIT | input | When held high this input blocks counter advancement via the CLOCK line; it can also be used as a negative-edge clock input when the CLOCK line is held high. |
| 3 | DISPLAY ENABLE IN | input | When low, forces the seven decoded outputs (a-g) low regardless of counter state, enabling low-power multiplexed-display operation; outputs go high on selection only when this pin is high. |
| 4 | DISPLAY ENABLE OUT | output | Display-enable output associated with the DISPLAY ENABLE IN gating function, used to cascade display-enable/multiplex control to additional decade stages. |
| 5 | CARRY OUT | output | Completes one cycle every ten CLOCK input cycles and is used to clock the succeeding decade directly in a multi-decade counting chain; not gated by DISPLAY ENABLE and therefore available continuously. |
| 6 | f | output | Decoded 7-segment output f; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 7 | g | output | Decoded 7-segment output g; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 8 | VSS | power_in | Negative supply/ground reference terminal; all voltages including VDD are referenced to VSS. |
| 9 | d | output | Decoded 7-segment output d; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 10 | a | output | Decoded 7-segment output a; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 11 | e | output | Decoded 7-segment output e; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 12 | b | output | Decoded 7-segment output b; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 13 | c | output | Decoded 7-segment output c; illuminates the corresponding display segment, going high on selection only when DISPLAY ENABLE IN is high. |
| 14 | UNGATED "C" SEGMENT OUT | output | Ungated version of the c-segment decoder output that is not gated by DISPLAY ENABLE and is available continuously, required for implementing divide-by-60/divide-by-12 divider functions. |
| 15 | RESET | input | A high level on this pin clears the decade counter to its zero count. |
| 16 | VDD | power_in | Positive supply pin; absolute maximum DC supply-voltage range referenced to VSS is -0.5 V to +20 V, with a recommended operating supply range of 3 V to 18 V. |
