General Characteristics
damage to the device.
The 56F807 DC/AC electrical specifications are preliminary and are from design simulations. These
specifications may not be fully tested or guaranteed at this early stage of the product life cycle. Finalized
specifications will be published after complete characterization and device qualifications have been
completed.
CAUTION
This device contains protective circuitry to guard against
damage due to high static voltage or electrical fields. However,
normal precautions are advised to avoid application of any
voltages higher than maximum rated voltages to this
high-impedance circuit. Reliability of operation is enhanced if
unused inputs are tied to an appropriate voltage level.
