Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the MK74CB218. These ratings, which
are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of the device at
these or any other conditions above those indicated in the operational sections of the specifications is not implied.
Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical
parameters are guaranteed only over the recommended operating temperature range.
DC Electrical Characteristics
Unless stated otherwise, VDD = 3.3 V ±10%
Note: Short circuits may be applied indefintely, but only one output may be shorted at a time to prevent exceeding
the power dissipation rating of this package.
