Wuxi I-core Elec · Registers · SOP-14
AIP74HC164SA14.TR from Wuxi I-core Elec, in a SOP-14. 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 | DSA | input | Serial data input; either DSA or DSB can be used as an active HIGH enable for data entry through the other input. |
| 2 | DSB | input | Serial data input; either DSA or DSB can be used as an active HIGH enable for data entry through the other input. |
| 3 | Q0 | output | Parallel data output 0 (first stage of the shift register). |
| 4 | Q1 | output | Parallel data output 1. |
| 5 | Q2 | output | Parallel data output 2. |
| 6 | Q3 | output | Parallel data output 3. |
| 7 | GND | power_in | Ground (0 V). |
| 8 | CP | input | Clock input, data shifts on the LOW-to-HIGH edge. |
| 9 | MR | input | Asynchronous master reset input, active LOW; a LOW clears the register and forces all outputs LOW independently of other inputs. |
| 10 | Q4 | output | Parallel data output 4. |
| 11 | Q5 | output | Parallel data output 5. |
| 12 | Q6 | output | Parallel data output 6. |
| 13 | Q7 | output | Parallel data output 7. |
| 14 | VCC | power_in | Supply voltage; 2.0 V to 6.0 V recommended for AiP74HC164 (absolute maximum 7 V). |
