MC74HC595ADR2G from onsemi, in a SOIC-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 | Parallel output QB, 3-state, noninverted latch output. |
| 2 | QC | tri_state | Parallel output QC, 3-state, noninverted latch output. |
| 3 | QD | tri_state | Parallel output QD, 3-state, noninverted latch output. |
| 4 | QE | tri_state | Parallel output QE, 3-state, noninverted latch output. |
| 5 | QF | tri_state | Parallel output QF, 3-state, noninverted latch output. |
| 6 | QG | tri_state | Parallel output QG, 3-state, noninverted latch output. |
| 7 | QH | tri_state | Parallel output QH, 3-state, noninverted latch output. |
| 8 | GND | power_in | Ground, return path for supply current. |
| 9 | SQH | output | Noninverted serial data output, eighth stage of shift register, no 3-state capability. |
| 10 | RESET | input | Active-low asynchronous shift register reset input; low resets shift register only. |
| 11 | SHIFT CLOCK | input | Shift register clock input; low-to-high transition shifts data into 8-bit shift register. |
| 12 | LATCH CLOCK | input | Storage latch clock input; low-to-high transition latches shift register data to outputs. |
| 13 | OUTPUT ENABLE | input | Active-low output enable; low enables data from latches at outputs, high forces high-impedance. |
| 14 | A | input | Serial data input; data on this pin is shifted into 8-bit serial shift register. |
| 15 | QA | tri_state | Parallel output QA, 3-state, noninverted latch output. |
| 16 | VCC | power_in | Positive supply voltage, 2.0 to 6.0 V recommended operating range. |
