Integrated Device Technology 

4:1, SINGLE-ENDED MULTIPLEXER

ICS83054I

GENERAL DESCRIPTION

The ICS83054I is a low skew, 4:1, Single-ended

ICS

Multiplexer and a member of the HiPerClockS™

HiPerClockS™ family of High Performance Clock Solutions from

IDT. 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 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.

FEATURES

• 4:1 single-ended multiplexer

• Q nominal output impedance: 7Ω (VDDO = 3.3V)

• Maximum output frequency: 250MHz

• Propagation delay: 3ns (maximum), V = V = 3.3V
