(1) The VTT_EN and ODT_EN pins has 6MΩ weak pull-down resistor to GND to make its default value to be LOW.
(2) For VTT_EN= L and ODE_EN= H, the TS3DDR32611 will also stays in the power down mode. However, there will be an increased
leakage current of up to max 25µA depending on the voltage level of ODT_EN and is thus not a recommended setting to use.

(1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may
degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond
those specified is not implied.
(2) The algebraic convention, whereby the most negative value is a minimum and the most positive value is a maximum.
(3) All voltages are with respect to GND, unless otherwise specified.
