Differential Input: These input pairs are the differential signal inputs to the device. They
accept differential 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. Please refer to the
“
Input Interface Applications
”
section for more details.

VT0, VT1
Input Termination Center-Tap: Each side of the differential input pair terminates to a V
T
pin. The V
T0
and V
T1
pins provide a center-tap to a termination network for maximum
interface flexibility. See
“
Input Interface Applications
”
section for more details.

SEL
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.
