ICS581-01 Datasheet, PDF (5/10 Pages) Integrated Circuit Systems – Zero-Delay Glitch-Free Clock Multiplexer

ICS581-01/02
ZERO DELAY GLITCH-FREE CLOCK MULTIPLEXER
ZDB AND MULTIPLEXER
External Components
The ICS581-01 and ICS581-02 require two 0.01F capacitors between VDD and GND, one on each side of the
chip. These must be close to the chip to minimize lead inductance. Series termination resistors of 33 should be
used on the outputs, should also be close to the chip, and the feedback path should be a direct connection from a
clock output to a FBIN pin, routed directly under the chip to minimize trace length. This should be connected before
the series termination resistor.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS581-01/02. 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.
