LVDS Differential (Outputs): Normally terminated with 100 across the pair (Q, /Q). See LVDS
Outputs section for more details.Unused outputs should be terminated with a 100 resistor across
each pair.
8 EN
The single-ended, TTL/CMOS-compatible input functions as a synchronous output enable. The
synchronous enable ensures that enable/disable will only occur when the outputs are in a logic LOW
state. Note that this input is internally connected to a 25k -pull up resistor and will default to logic
HIGH state (enabled) if left open.
9, 12 /IN, IN
Differential Inputs: These input pairs are the differential signal inputs to the device. Inputs accept AC-
or DC-Coupled differential signs 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 intermediate state if left open. See Input
Interface Applications section for more details.
10 VREF-AC
Reference Voltage: These outputs bias to VCC1.4V. They are used when AC coupling the inputs
(IN, /IN). For AC-Coupled applications, connect VREF-AC to VT pin and bypass with 0.0F low
ESR capacitor to VCC. See Input Interface Applications section for more details.
Maximum sink/source current is ±1.5mA. Due to the limited drive capability, each VREF-AC pin is
only intended to drive its respective VT pin.
11 VT
Input Termination Center Tap: Each side of the differential input pair terminates to a VT pin. The-
VT pins provide a center tap to a termination network for maximum interface flexibility. See - Input
Interface Applications section for more details.
13 GND
Ground. GND pins and exposed pad must be connected to the most negative potential of the device
ground.
7, 14 VCC
Positive Power Supply: Bypass with 0.1μF//0.01μF low ESR capacitors and place as close to each
VCC pin as possible.
