www.DataSheet4U.com Micrel, Inc. 4:1 DIFFERENTIAL MULTIPLEXER SY10EL57 SY100EL57 SY10EL57 SY100EL57 FEATURES s Useful as either 4:1 or 2:1 multiplexer s VBB output for single-ended operation s 75KΩ internal input pulldown resistors s Available in 150 mil 16-pin SOIC package DESCRIPTION The SY10/100EL57 are fully differential 4:1 multiplexers. 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 0.01µF capacitor to ground. Note that the VBB output can source/sink up to 0.5mA of current without upsetting the voltage level.
