Power Down Timing
NOTE 1: It is recommended that outputs be disabled before entering power-down mode. It is also recommended that the outputs remain
disabled until the device completes power-up after asserting PD.
NOTE 2: The Power Down Timing diagram assumes that GL is HIGH.
NOTE 3: It should be noted that during power-down mode, the outputs are both pulled to V
DD
. In the Power Down Timing diagram this is
shown when Qn/Qn goes to V
DIF
= 0.
