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
V
DDO
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.
