5. All Q values are reset to LOW when
MR
goes low.
MR
is asynchronous and overrides all other signals.
6. Serial data supplied at DSA and DSB is ANDED and transferred to Q0 on positive edge of CP.

7. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should
be within recommend values.
8. Input Voltage cannot exceed Vcc to the extent the maximum clamp current is exceeded.
