SCDS192A – APRIL 2005 – REVISED FEBRUARY 2016
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The SN74CBTU4411 is suitable for DDR-II applications where high-bandwidth is required. This device has low
and flat ON resistance and have internal termination control inputs. The D-ports are precharged by Bias voltage.
9.2 Typical Application
SN74CBTU4411 is an 11 bit, 1:4 Mux and suitable for high-bandwidth applications.

9.2.1 Design Requirements
SN74CBTU4411 supports 400-MHz bandwidth on the D or H ports and 84 MHz on the S port. The Enable
control from the master must be activated and depending on the select pins, the data is transferred into one of
the slaves 0 to 3. The Enable control at high will tristate the Input / output as per the functional table. See
Recommended Operating Conditions and Absolute Maximum Ratings for other voltage, current and handling
parameters.
