CDCLVC1103: continuous output current

Part Number: CDCLVC1103

Hi guys,


Quick question about the CDCLVC1103 1:3 clock buffer:  the datasheet lists the continuous output current as 50 mA absolute maximum.  Can you help clarify if that’s per output, or total amongst all outputs?  I am looking at an application where I need to fan out a CMOS clock into two-three 50 ohm loads.


  • Hello Michael,

    This spec is per output.

    Note, when LVCMOS is driving 50 ohm loads, I often AC couple.  This way LVCMOS is driving (at least from DC perspective) high impedance as intended.  Then the receiver can bias to it's own ideal range.
