Differential Inputs: These inputs accept AC- or DC-coupled signals as small as 100mV.
Each pin of a pair internally terminates to a V
T
pin through 50
. Note that these
inputs will default to an indeterminate state if left open. If an input pair is not used, connect
one input of the pair to ground through a 1k
resistor and the complement to V
CC
through a
825
resistor. Unused V
T
and V
REF-AC
may also be left open. Please refer to the
“
Input
Interface Applications
”
section for more details.
Input Termination Center-Tap: Each side of the differential input pair terminates to a V
T
pin. The V
T
pin provides a center-tap to the termination network for maximum
interface flexibility. See
“
Input Interface Applications
”
section for more details.
This single-ended TTL/CMOS compatible input selects the inputs to the multiplexer. Note
that this input is internally connected to a 25k
pull-up resistor and will default to a logic
HIGH state if left open. Input logic threshold is V
CC
/2. See
“
Truth Table
”
for select control.

Differential Outputs: These CML output pairs are copies of the selected input. Unused
output pairs may be left floating. See

section for termination guidelines.
Ground. Ground pin and exposed pad must be connected to the same ground plane.

Reference Voltage: This reference output is equivalent to V
CC
–
1.4V. It is used for AC-coupled
inputs. When interfacing to AC input signals, connect V
REF-AC
directly to the V
T
pin and
bypass with 0.01
μ
F low ESR capacitor to V
CC
. See
“

”
section.
Maximum sink/source current is 0.5mA.
