SN74HC393PWR from Texas Instruments, in a TSSOP-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 | Counter 1 Clock Input for incrementing the counter on each clock pulse. |
| 2 | 1CLR | input | Counter 1 Clear Input to reset all counter outputs to logic low. |
| 3 | 1QA | output | Counter 1 A Output, least significant bit of the 4-bit counter. |
| 4 | 1QB | output | Counter 1 B Output, second stage of the 4-bit counter. |
| 5 | 1QC | output | Counter 1 C Output, third stage of the 4-bit counter. |
| 6 | 1QD | output | Counter 1 D Output, most significant bit of the 4-bit counter. |
| 7 | GND | power_in | Ground connection for the device. |
| 8 | 2QD | output | Counter 2 D Output, most significant bit of the second 4-bit counter. |
| 9 | 2QC | output | Counter 2 C Output, third stage of the second 4-bit counter. |
| 10 | 2QB | output | Counter 2 B Output, second stage of the second 4-bit counter. |
| 11 | 2QA | output | Counter 2 A Output, least significant bit of the second 4-bit counter. |
| 12 | 2CLR | input | Counter 2 Clear Input to reset all outputs of the second counter to logic low. |
| 13 | 2CLK | input | Counter 2 Clock Input for incrementing the second counter on each clock pulse. |
| 14 | VCC | power_in | VCC Power Supply, 2 V to 6 V operating range. |
