MC100EL57

` Useful as Either 4:1 or 2:1 Multiplexer
` VBB Output for Single-Ended Operation
` 75k Internal Input Pulldown Resistors
` >1000V ESD Protection

The MC100EL57 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 MC100EL57 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 V_BB output should be connected to the data bar inputs and bypassed via a 0.01F capacitor to ground. Note that the V_BB output can source/sink up to 0.5mA of current without upsetting the voltage level.
