SN74LV594APWR 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 | QB | output | Parallel output from stage B of the 8-bit shift register. |
| 2 | QC | output | Parallel output from stage C of the 8-bit shift register. |
| 3 | QD | output | Parallel output from stage D of the 8-bit shift register. |
| 4 | QE | output | Parallel output from stage E of the 8-bit shift register. |
| 5 | QF | output | Parallel output from stage F of the 8-bit shift register. |
| 6 | QG | output | Parallel output from stage G of the 8-bit shift register. |
| 7 | QH | output | Parallel output from stage H of the 8-bit shift register. |
| 8 | GND | power_in | Ground pin; 0V reference. |
| 9 | QH' | output | Serial output (QH inverted) for cascading purposes. |
| 10 | SRCLR | input | Independent direct overriding clear input for shift register; active low. |
| 11 | SRCLK | input | Positive-edge triggered clock input for shift register. |
| 12 | RCLK | input | Positive-edge triggered clock input for storage register. |
| 13 | RCLR | input | Independent direct overriding clear input for storage register; active low. |
| 14 | SER | input | Serial data input to 8-bit shift register. |
| 15 | QA | output | Parallel output from stage A of the 8-bit shift register. |
| 16 | Vcc | power_in | Positive supply voltage; recommended operating range 2V to 5.5V. |
