positive-edge trigger
74AHC377; 74AHCT377
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;
X = don’t care;
↑ = LOW-to-HIGH CP transition.
