Input Capacitance
Note 1 ‘‘Absolute Maximum Ratings’’ are the values beyond which the safety of the device cannot be guaranteed They are not meant to imply that the device
should be operated at these limits The table of ‘‘Electrical Characteristics’’ provides conditions for actual device operation
Note 2 All typical values are for T
Note 3 This test is provided as a monitor of Driver output source and sink current capability Caution should be exercised in testing this parameter In testing these
parameters a 15
