SY10EL57 4:1 DIFFERENTIAL
MULTIPLEXER Micrel, Inc. FEATURES SY100EL57 DESCRIPTION в– 5V power supply
в– Useful as either 4:1 or 2:1 multiplexer
в– VBB output for single-ended operation
■75KΩ internal input pulldown resistors
в– Available in 150 mil 16-pin SOIC package 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 0.01ВµF capacitor to ground. Note that the VBB output
can source/sink up to 0.5mA of current without upsetting …
