SY10EL57
SY1S0YE1L005E7L57
SY100EL57
FEATURES
s Useful as either 4:1 or 2:1 multiplexer
s VBB output for single-ended operation
s 75Kinternal 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.

Note:
1. 10EL circuits are designed to meet the DC specifications shown in the table after thermal equilibrium has been established. The circuit is in a test
socket or mounted on a printed circuit board and transverse airflow greater than 500lfpm is maintained. Outputs are terminated through a 50
resistor to -2.0V except where otherwise specified on the individual data sheets.
