83052AGILFT集成电路（IC）的时钟缓冲器驱动器规格书PDF中文资料

GENERAL DESCRIPTION

The ICS83052I is a low skew, 2:1, Single-ended Multiplexer. The ICS83052I has two 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. The device operates up to 250MHz and is packaged in an 8 TSSOP.
