74AHC594T16-13 from Diodes Incorporated, 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 | Q1 | output | Parallel data output 1 of the storage register, push-pull. |
| 2 | Q2 | output | Parallel data output 2 of the storage register, push-pull. |
| 3 | Q3 | output | Parallel data output 3 of the storage register, push-pull. |
| 4 | Q4 | output | Parallel data output 4 of the storage register, push-pull. |
| 5 | Q5 | output | Parallel data output 5 of the storage register, push-pull. |
| 6 | Q6 | output | Parallel data output 6 of the storage register, push-pull. |
| 7 | Q7 | output | Parallel data output 7 of the storage register, push-pull. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | Q7S | output | Serial data output used for cascading information between devices. |
| 10 | SHR | input | Shift register reset, active low; sets all shift register values to zero and is independent of all clocks. |
| 11 | SHCP | input | Shift register clock; data is accepted from DS on each positive transition. |
| 12 | STCP | input | Storage register clock; a rising pulse places shift register data into the output register. |
| 13 | STR | input | Storage register reset, active low; sets all shift register values to zero and is independent of all clocks. |
| 14 | DS | input | Serial data input to the shift register, with Schmitt trigger action and inputs accepting up to 5.5V. |
| 15 | Q0 | output | Parallel data output 0 of the storage register, push-pull. |
| 16 | VCC | power_in | Supply voltage, specified from 2.0V to 5.5V. |
