74AHC164S14-13 from Diodes Incorporated, in a SO-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; data on DSA and DSB is logically ANDED and must be stable before and after the CP rising edge to meet set-up and hold timing. |
| 2 | DSB | input | Serial data input; data on DSB is logically ANDED with DSA and must be stable before and after the CP rising edge to meet set-up and hold timing. |
| 3 | Q0 | output | Data output for stage 0; receives the ANDed serial input data on each LOW-to-HIGH transition of CP and is set LOW by MR. |
| 4 | Q1 | output | Data output for stage 1; takes the value of Q0 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 5 | Q2 | output | Data output for stage 2; takes the value of Q1 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 6 | Q3 | output | Data output for stage 3; takes the value of Q2 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 7 | GND | power_in | Ground reference pin. |
| 8 | CP | input | Clock pulse input, positive-edge triggered; shifts data into Q0 and through Qn on each LOW-to-HIGH transition. |
| 9 | MR | input | Asynchronous active-LOW master reset; when LOW sets all Qn LOW regardless of serial or clock inputs, and must return HIGH for a recovery time before the next CP positive edge. |
| 10 | Q4 | output | Data output for stage 4; takes the value of Q3 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 11 | Q5 | output | Data output for stage 5; takes the value of Q4 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 12 | Q6 | output | Data output for stage 6; takes the value of Q5 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 13 | Q7 | output | Data output for stage 7; takes the value of Q6 on each LOW-to-HIGH CP transition and is set LOW by MR. |
| 14 | VCC | power_in | Supply voltage; recommended operating range is 2.0 V to 5.5 V. |
