Establishing Static Logic Inputs
The true pin of an input pair is internally biased to ground
through a 75k
resistor. The complement pin of an input
pair is internally biased halfway between V
CC
and ground
by a voltage divider consisting of two 75k
resistors. In this
way, unconnected inputs appear as logic zeros. To keep an
input at static logic zero at V
CC
> 3.0V, leave both inputs
unconnected. For V
CC
≤
3.0V, connect the complement
input to V
CC
and leave the true input unconnected. To make
an input static logic one, connect the true input to V
CC
,
leave the complement input unconnected. These are the
only two safe ways to cause inputs to be at a static value.
In particular, no input pin should be directly connected to
ground. All NC (no connect) pins should be unconnected.
Note 1.
X is either D0, D1, S0, or S1 input. /X is either /D0, /D1, /S0, or
/S1 input.
Usage
SY55854U is very versatile. Tying its select inputs in
various ways varies its functionality. For example, tying the
select inputs together turns SY55854U into a redundant
distributor. Either input will be switched to both outputs
simultaneously. This is very useful in redundant backplane
applications. By cross-tying the select inputs, SY55854U
becomes a true crosspoint, selecting between
“
straight
through
”
and
“
cross connected
”
operation. Also, using the
select inputs independently, SY55854U functions as two
multiplexers. Setting the select inputs to static values turns
SY55854U into a dual buffer, or a fan-out buffer.
To make larger crosspoints, cascade SY55854U devices,
either in a tree or in a Banyan structure, as appropriate for
your application.
