FUNCTION TABLE
See note 1.
Note
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;
Z = high-impedance OFF-state;
↑
= LOW-to-HIGH CP transition.
