Integrated Circuit Systems, Inc. 4:1, SINGLE-ENDED MULTIPLEXER Features - 4:1 single-ended multiplexer - Q nominal output impedance: 7Ω (VDDO =3 .3V) - Maximum output frequency: 250MHz - Propagation delay: 3ns (maximum), VDD = VDDO = 3.3V - Input skew: 225ps (maximum), VDD = VDDO = 3.3V - Part-to-part skew: 475ps (maximum), VDD = VDDO = 3.3V - Operating supply modes: VDD/VDDO 3.3V/3.3V 3.3V/2.5V 3.3V/1.8V 2.5V/2.5V 2.5V/1.8V - -40°C to 85°C ambient operating temperature - Available in both standard and lead-free Ro HS-pliant packages GENERAL DESCRIPTION The ICS83054I is a low skew, 4:1, Singleended Multiplexer and a member of the Hi Per Clock S™ Hi Per Clock S ™ 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 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.
