The output is high impedance when the device is in shutdown mode. Note that this feature must be used with care because the enable/disable time is much longer
than with a true tristate output.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
