56F802 Technical Data, Rev. 9

Freescale Semiconductor

The 56F802 DC and 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

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.
