Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A1 | input | Serial data input; a high level is entered into the first stage only when both A1 and A2 are high, so one input can serve as a data enable, and an unused serial input must be tied to VCC. |
| 2 | A2 | input | Serial data input; a high level is entered into the first stage only when both A1 and A2 are high, so one input can serve as a data enable, and an unused serial input must be tied to VCC. |
| 3 | QA | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 4 | QB | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 5 | QC | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 6 | QD | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 7 | GND | power_in | Ground reference pin for all voltages (VCC range 2.0 V to 6.0 V referenced to GND). |
| 8 | CLOCK | input | Shift register clock; data shifts to the next stage on each positive-going transition, and the register is static so clock rates down to DC are allowed. |
| 9 | RESET | input | Active-low asynchronous reset; a low level resets all flip-flops and forces QA-QH low, overriding the clock and serial data inputs. |
| 10 | QE | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 11 | QF | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 12 | QG | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 13 | QH | output | Parallel shift register output, presented in true (non-inverted) form; unused outputs must be left open. |
| 14 | VCC | power_in | Positive supply pin; the recommended operating range is 2.0 V to 6.0 V and the absolute maximum is -0.5 V to +7.0 V referenced to GND. |
