DC Electrical Characteristics table). Add 10.4mA to get
the total approximate maximum supply current at V
= 5.5V and V
If the output supply voltage is less than V
the reduced supply current can be calculated using the
same formula and method.
At high switching frequency, high supply voltage, and
high capacitive loading, power dissipation can exceed

the package power-dissipation rating. Do not exceed
the maximum package power-dissipation rating. See
the Absolute Maximum Ratings for maximum package
power-dissipation capacity and temperature derating.
The MAX9234 has a rising-edge output strobe, which
latches the parallel output data into the next chip on the
rising edge of RxCLK OUT. The MAX9236/MAX9238
have a falling-edge output strobe, which latches the
parallel output data into the next chip on the falling
edge of RxCLK OUT. The deserializer output strobe
polarity does not need to match the serializer input
strobe polarity. A deserializer with rising- or falling-
edge output strobe can be driven by a serializer with a
rising-edge input strobe.
