GENERAL DESCRIPTION
The ICS83058I is a low skew, 8:1, Single-ended Multiplexer and a member of the HiPerClockSTM HiPerClockSTM family of High Performance Clock Solutions from ICS. The ICS83058I has eight selectable singleended 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 packaged in a 16 TSSOP.

8:1, SINGLE-ENDED MULTIPLEXER APPLICATION INFORMATION
RECOMMENDATIONS FOR UNUSED INPUT PINS 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 1kW resistor can be tied from the CLK input to ground. 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 1k resistor can be used.
