Differential Inputs: These inputs pairs are the differential signal inputs to the device. Inputs
accept AC- or DC-coupled signals as small as 100mV. Each pin of a pair internally terminates to
a VT pin through 50. Note that these inputs will default to an indeterminate state if left open.
Unused differential input pairs can be terminated by connecting one input to VCC and the
complementary input to GND through a 1k resistor. The VT pin is to be left open in this
configuration. Please refer to the “input Interface Applications” section for more details.
3, 31, 26, 22
VT0, VT1,
VT2, VT3
Input Termination Center-Tap: Each side of the differential input pair, terminates to a VT pin.
The VTA0, VTA1, VTB0, VTB1 pins provide a center-tap to a termination network for maximum
interface flexibility. See “input Interface Applications” section for more details.
6, 19
SEL0, SEL1
These single-ended TTL/CMOS-compatible inputs select the inputs to the multiplexers. Note
that these inputs are internally connected to a 25k pull-up resistor and will default to a logic
HIGH state if left open. Input switching threshold is VCC/2.

Positive Power Supply: Bypass with 0.1μF║ 0.01μF low ESR capacitors.

Q0, /Q0
Q1, /Q1
Differential Outputs: These LVDS outputs pairs are the outputs of the device. They are a logic
function of the INA0, INA1, INB0, INB1 and SELA and SELB inputs. Please refer to the “Truth
Table” for details. If an output is not used, it must be terminated with 100 across the
differential pair.
7, 9, 12, 13,
16, 18
GND,
Exposed pad
Ground: Ground pin and exposed pad must be connected to the same ground plane.
