## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | STROBE | input | Strobe input: when high, the data in each shift register stage is transferred to the storage register. |
| 2 | DATA | input | Serial data input to the 8-stage shift register, shifted in on positive clock transitions. |
| 3 | CP | input | Clock input: data is shifted on positive clock transitions, and QS1 and QS2 provide serial outputs on the positive and following negative clock edges. |
| 4 | Q0 | tri_state | Three-state parallel output Q0; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 5 | Q1 | tri_state | Three-state parallel output Q1; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 6 | Q2 | tri_state | Three-state parallel output Q2; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 7 | Q3 | tri_state | Three-state parallel output Q3; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 8 | GND | power_in | Ground reference pin. |
| 9 | QS1 | output | Serial output available on positive clock edges, allowing high-speed operation in cascaded systems where the clock rise time is fast. |
| 10 | QS2 | output | Serial output available on the next negative clock edge, provided for cascading when the clock rise time is slow. |
| 11 | Q7 | tri_state | Three-state parallel output Q7; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 12 | Q6 | tri_state | Three-state parallel output Q6; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 13 | Q5 | tri_state | Three-state parallel output Q5; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 14 | Q4 | tri_state | Three-state parallel output Q4; data appears here when OE is high and the outputs may be connected directly to common bus lines. |
| 15 | OE | input | Output enable: parallel outputs Q0 to Q7 show the storage register data only while OE is high; when low they are high-impedance. |
| 16 | VCC | power_in | Supply voltage: 2 V to 6 V for HC types (4.5 V to 5.5 V for HCT types), per the operating conditions. |
