8.1 Frequently asked questions
Question 1: When the GTL2009 is unpowered, the LVTTL inputs may be pulled up to
3.3 V and we want to make sure that there is no leakage path to the power rail under this
condition. Are the LVTTL inputs high-impedance when the device is unpowered and will
there be any leakage?
Answer 1: When the device is unpowered, the LVTTL inputs will be in a high-impedance
state and will not leak to V
unpowered.
Question 2: What is the condition of the GTL and LVTTL output pins when the device is
unpowered?
Answer 2: The open-drain GTL outputs will not leak to the power supply if they are pulled
HIGH or allowed to float while the device is unpowered. The GTL inputs will also not leak
to the power supply under the same conditions. The LVTTL totem pole outputs, however,
are not open-drain type outputs and there will be current flow on these pins if they are
pulled HIGH when V
