SCAN Circuitry Timing Requirements
Over recommended operating supply and temperature ranges unless otherwise specified.
Note 1: “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply that the devices
should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
Note 2: Typical values are given for V
Note 3: Current into device pins is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to ground except VOD, and
ΔVOD which are differential voltages.
Note 4: BIST_SEL have a weak internal pull-up. In a noisy operating environment, it is recommended that an external pull up be used to ensure that BIST_SEL
is in the high state.
Note 5: t
