4-bit bidirectional universal shift register
5.2 Pin description
6. Functional description
[1] H = HIGH voltage level;
h = HIGH voltage level one set-up time prior to the LOW-to-HIGH CP transition;
L = LOW voltage level;
I = LOW voltage level one set-up time prior to the LOW-to-HIGH CP transition;
q, d = lower case letters indicate the state of the referenced input (or output) one set-up time prior to the LOW-to-HIGH CP transition;
X = don’t care;
= LOW-to-HIGH clock transition.

7. Limiting values
[1] For SO16 packages: above 70 C the value of P
tot
derates linearly at 8 mW/K.
For SSOP16 packages: above 60 C the value of P
tot
derates linearly at 5.5 mW/K.
Typical timing sequence:
Typical clear-load; shift-right; shift-left; inhibit and clear timing sequences.
