ICS83054I
4:1, SINGLE-ENDED MULTIPLEXER
GENERAL DESCRIPTION
The ICS83054I is a low skew, 4:1, Single-
ended Multiplexer and a member of the
HiPerClockS™ family of High Performance
Clock Solutions from ICS. The ICS83054I
has four selectable single-ended clock inputs
and one single-ended clock output. The output has a
VDDO pin which may be set at 3.3V, 2.5V, or 1.8V, making
the device ideal for use in voltage translation applications.
An output enable pin places the output in a high
impedance state which may be useful for testing or
debug. The device operates up to 250MHz and is pack-
aged in a 16 TSSOP.

APPLICATION INFORMATION
INPUTS:
CLK INPUT:
For applications not requiring the use of a clock input, it can
be left floating. Though not required, but for additional
protection, a 1kΩ resistor can be tied from the CLK input to
ground.
RECOMMENDATIONS FOR UNUSED INPUT PINS
LVCMOS CONTROL PINS:
All control pins have internal pull-ups or pull-downs;
additional resistance is not required but can be added for
additional protection. A 1kΩ resistor can be used.
