DESCRIPTION
The AZ10/100EL57 is a fully differential 4:1 multiplexer. By leaving the SEL1 line open (pulled LOW via the
input pulldown resistor) the device can also be used as a differential 2:1 multiplexer with the 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.
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, 01 selects D1, etc.).
The EL57 provides two VBB outputs for single-ended use or a DC bias reference for AC coupling to the device.
For single-ended input applications, the VBB reference should be connected to one side of the Dn/D¯ n differential
input pair. The input signal is then fed to the other Dn/D¯ n input. The VBB pins should be used only as a bias for the
EL57 as its current sink/source capability is limited. When used, the VBB pins should be bypassed to ground via a
0.01µF capacitor.
NOTE: Specifications in the ECL/PECL tables are valid when thermal equilibrium is established.
