MOTOROLA MC10EL57/MC100EL57 handbook

The EL57 is a fully differential 4:1 multiplexer which can also be used as a differential 2:1 multiplexer with the SEL0 input selecting between D0 and D1. The EL57’s fully differential architecture makes it ideal for use in low skew applications such as clock distribution. 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 0.01µF capacitor to ground. Note that the VBB output can source/sink up to 0.5mA of current without upsetting the voltage level.
