Pin Function

1, 4

IN, /IN

Differential Input: This input pair is the signal to be buffered. These inputs accept AC or DC-

coupled signals as small as 100mV. Each pin of this pair internally terminates to a VT pin

through 50

Ω. Note that this input will default to an indeterminate state if left open. Please

refer to the “Input Interface Applications” section for more details.

2

VT

Input Termination Center-Tap: Each side of the differential input pair terminates to this pin.

The VT pin provides a center-tap to a termination network for maximum interface flexibility.

See “Input Interface Applications” section for more details.

3

VREF-AC

Reference Output Voltage: This output biases to V

coupling the input. Bypass with 0.01

µF low ESR capacitor to V

or sink is 0.5mA. See “Input Interface Applications” section.

8

VCC

Positive Power Supply. Bypass with 0.1

µF||0.01µF low ESR capacitors as close to the VCC

pin as possible.

7, 6

Q, /Q

Differential CML Output: Differential buffered output copy of the input signal. The differential

output swing is typically 800mV into a 50

Ω load, or 100Ω across the pair. See “Output

Interface Applications” section.
