SN74HC393DR from Texas Instruments, in a SOIC-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 | 1CLK | input | Clock input for Counter 1; counter advances on rising edge. |
| 2 | 1CLR | input | Asynchronous clear input for Counter 1; high level clears all counter outputs to 0. |
| 3 | 1QA | output | Counter 1 Q output stage A, least significant bit of 4-bit counter. |
| 4 | 1QB | output | Counter 1 Q output stage B, second stage of 4-bit counter. |
| 5 | 1QC | output | Counter 1 Q output stage C, third stage of 4-bit counter. |
| 6 | 1QD | output | Counter 1 Q output stage D, most significant bit of 4-bit counter. |
| 7 | GND | power_in | Ground, return path for all signal and supply voltages. |
| 8 | 2QD | output | Counter 2 Q output stage D, most significant bit of 4-bit counter. |
| 9 | 2QC | output | Counter 2 Q output stage C, third stage of 4-bit counter. |
| 10 | 2QB | output | Counter 2 Q output stage B, second stage of 4-bit counter. |
| 11 | 2QA | output | Counter 2 Q output stage A, least significant bit of 4-bit counter. |
| 12 | 2CLR | input | Asynchronous clear input for Counter 2; high level clears all counter outputs to 0. |
| 13 | 2CLK | input | Clock input for Counter 2; counter advances on rising edge. |
| 14 | VCC | power_in | Positive supply voltage; 2V to 6V per recommended operating conditions. |
