4:1 Differential Multiplexer

The MC10/100EL57 is a fully differential 4:1 multiplexer. By leaving the

SEL1 line open (pulled LOW via the input pulldown resistors) the device

can also be used as a differential 2:1 multiplexer with SEL0 input

selecting between D0 and D1. The fully differential architecture of the

EL57 makes it ideal for use in low skew applications such as clock

distribution.

The SEL1 is the most significant select line. The binary number applied

to the select inputs will select the same numbered data input (i.e., 00

selects D0).

Multiple VBB outputs are provided for single-ended or AC coupled

interfaces. In these scenarios, the VBB output should be connected to the

data bar inputs and bypassed via a 0.01

µF capacitor to ground. Note that

the VBB output can source/sink up to 0.5mA of current without upsetting

the voltage level.
