74VHC595FT from TOSHIBA, in a TSSOP-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | QB | tri_state | 3-state parallel output B of the storage register. |
| 2 | QC | tri_state | 3-state parallel output C of the storage register. |
| 3 | QD | tri_state | 3-state parallel output D of the storage register. |
| 4 | QE | tri_state | 3-state parallel output E of the storage register. |
| 5 | QF | tri_state | 3-state parallel output F of the storage register. |
| 6 | QG | tri_state | 3-state parallel output G of the storage register. |
| 7 | QH | tri_state | 3-state parallel output H of the storage register. |
| 8 | GND | power_in | Ground pin. |
| 9 | QH' | output | Serial data output from the end of the shift register, changing on SCK; delays given as SCK to QH'. |
| 10 | SCLR | input | Active-low shift register clear input; inputs accept 0 to 5.5 V regardless of VCC. |
| 11 | SCK | input | Shift register clock; shifts on the positive-going transition. |
| 12 | RCK | input | Storage register clock; loads the output register from the shift register on the positive-going transition. |
| 13 | G | input | Active-low output enable for the 3-state parallel outputs. |
| 14 | SI | input | Serial data input to the shift register; accepts 0 to 5.5 V. |
| 15 | QA | tri_state | 3-state parallel output A of the storage register. |
| 16 | VCC | power_in | Supply voltage, 2.0 V to 5.5 V operating range. |
