NOTE:
1. The
LBO
pin will be internally pulled to V
DD
if it is not actively driven in the application and the ZZ in will be internally pulled to V
SS
if not actively driven.
NOTES:
1. All values are maximumguaranteed values.
2. At f = f
MAX,
inputs are cycling at the maximumfrequency of read cycles of 1/t
