**onsemi** · Shift Registers · SOIC-16

MC14094BDR2G 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 | STROBE | input | Strobe input: data is latched on the negative transition of strobe, and data propagates through the latches while strobe is high. |
| 2 | DATA | input | Serial data input to shift register stage 1, shifted in on the positive clock transition. |
| 3 | CLOCK | input | Clock input: data shifts on the positive clock transition, and the Q'S serial output shifts on the following negative transition. |
| 4 | Q1 | tri_state | Parallel 3-state output of data latch 1, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 5 | Q2 | tri_state | Parallel 3-state output of data latch 2, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 6 | Q3 | tri_state | Parallel 3-state output of data latch 3, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 7 | Q4 | tri_state | Parallel 3-state output of data latch 4, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 8 | VSS | power_in | Negative supply and voltage reference for all ratings; inputs and outputs must stay within VSS ≤ (Vin or Vout) ≤ VDD. |
| 9 | QS | output | High-speed serial output from shift register stage 7, updated on the positive clock transition for cascaded systems. |
| 10 | Q'S | output | Low-speed serial output from shift register stage 7, shifted on the following negative clock transition for cascaded systems. |
| 11 | Q8 | tri_state | Parallel 3-state output of data latch 8, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 12 | Q7 | tri_state | Parallel 3-state output of data latch 7, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 13 | Q6 | tri_state | Parallel 3-state output of data latch 6, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 14 | Q5 | tri_state | Parallel 3-state output of data latch 5, placed in high impedance by a logic Low on Output Enable; rated to drive two low-power TTL loads over the rated temperature range. |
| 15 | OUTPUT ENABLE | input | A logic Low forces parallel outputs Q1 through Q8 into the high-impedance state; a logic High enables them. |
| 16 | VDD | power_in | Positive supply; the DC supply voltage range is −0.5 V to +18.0 V with respect to VSS (maximum ratings). |
