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 IDT. The ICS83054I has four 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 purposes. The device operates up to 250MHz and is packaged in a 16 TSSOP package.
