ICS671-15

External Components

The ICS671-15 requires a minimum number of external components for proper operation. Decoupling

capacitors of 0.1

µF should be connected between VDD and GND, as close to the part as possible. A 33 Ω

series terminating resistor should be used on each clock output to reduce reflections.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS671-15. These ratings,

which are standard values for ICS 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.
