ICS83058I Datasheet, PDF (1/14 Pages) Integrated Circuit Systems – 8:1, SINGLE-ENDED MULTIPLEXER

8:1, SINGLE-ENDED MULTIPLEXER
ICS83058I
GENERAL DESCRIPTION
The ICS83058I is a low skew, 8:1, Single-ended
ICS
Multiplexer and a member of the HiPerClockS™
HiPerClockS™ _{family of High Performance Clock Solutions from}
IDT. The ICS83058I has eight 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 trans-
lation 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.
