SN74HC4040PWR from Texas Instruments, in a TSSOP-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 | QL | output | Counter stage L output (Q12), one of the 12 asynchronous binary counter outputs available externally. |
| 2 | QF | output | Counter stage F output (Q6), one of the 12 asynchronous binary counter outputs available externally. |
| 3 | QE | output | Counter stage E output (Q5), one of the 12 asynchronous binary counter outputs available externally. |
| 4 | QG | output | Counter stage G output (Q7), one of the 12 asynchronous binary counter outputs available externally. |
| 5 | QD | output | Counter stage D output (Q4), one of the 12 asynchronous binary counter outputs available externally. |
| 6 | QC | output | Counter stage C output (Q3), one of the 12 asynchronous binary counter outputs available externally. |
| 7 | QB | output | Counter stage B output (Q2), one of the 12 asynchronous binary counter outputs available externally. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | QA | output | Counter stage A output (Q1), the first-stage output of the 12-bit binary counter, available externally. |
| 10 | CLK | input | Clock input; the count advances on a high-to-low transition at this pin. |
| 11 | CLR | input | Asynchronous clear input; a high level on CLR resets all 12 counter outputs low regardless of CLK. |
| 12 | QI | output | Counter stage I output (Q9), one of the 12 asynchronous binary counter outputs available externally. |
| 13 | QH | output | Counter stage H output (Q8), one of the 12 asynchronous binary counter outputs available externally. |
| 14 | QJ | output | Counter stage J output (Q10), one of the 12 asynchronous binary counter outputs available externally. |
| 15 | QK | output | Counter stage K output (Q11), one of the 12 asynchronous binary counter outputs available externally. |
| 16 | VCC | power_in | Supply voltage input; recommended operating range is 2 V to 6 V. |
