Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Q1 | tri_state | Parallel data output Q1 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 2 | Q2 | tri_state | Parallel data output Q2 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 3 | Q3 | tri_state | Parallel data output Q3 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 4 | Q4 | tri_state | Parallel data output Q4 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 5 | Q5 | tri_state | Parallel data output Q5 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 6 | Q6 | tri_state | Parallel data output Q6 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 7 | Q7 | tri_state | Parallel data output Q7 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 8 | GND | power_in | Ground reference (0 V) for all voltages referenced in the datasheet. |
| 9 | Q7S | output | Serial data output carrying shift register stage 7 for cascading to the DS input of another device; absolute max output current is ±25 mA. |
| 10 | MR | input | Asynchronous master reset, active LOW; a LOW resets only the shift register and does not affect the storage register. |
| 11 | SHCP | input | Shift register clock; data on DS is shifted in on each LOW-to-HIGH transition of SHCP. |
| 12 | STCP | input | Storage register clock; a LOW-to-HIGH transition transfers the shift register contents to the storage register and parallel outputs. |
| 13 | OE | input | Output enable, active LOW; a HIGH forces the Qn outputs to high-impedance OFF-state without changing the register contents. |
| 14 | DS | input | Serial data input to the shift register stage 0, sampled on the LOW-to-HIGH transition of SHCP. |
| 15 | Q0 | tri_state | Parallel data output Q0 from the storage register; goes to high-impedance OFF-state when OE is HIGH. |
| 16 | VCC | power_in | Supply voltage, recommended range 2.0 V to 6.0 V (absolute maximum 7.0 V). |
