shift register stages shifted through, e.g. previous state of stage 6
(internal Q6S) appears on the serial output (Q7S).
X H H X NC QnS contents of shift register stages (internal QnS) are transferred to
the storage register and parallel output stages

8. Limiting values
[1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
[2] For SO16 packages: above 70 C the value of P
tot
derates linearly at 8 mW/K.
For (T)SSOP16 packages: above 60 C the value of P
tot
derates linearly at 5.5 mW/K.
For DHVQFN16 packages: above 60 C the value of P
tot
derates linearly at 4.5 mW/K.
Table 4. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
