Description

VTD

−

Internal 50 W termination pin. See Table 4 (Note 1).

LVPECL, CML, HSTL,

LVCMOS, LVDS, LVTTL Input

Inverted differential input. Internal 36.5 kW to VCC and 73 kW to VEE

(Note 1).

LVPECL, CML, HSTL,

LVCMOS, LVDS, LVTTL Input

Noninverted differential input. Internal 73 kW to VCC and 36.5 kW to VEE

(Note 1).

VTD

−

Internal 50 W termination pin. See Table 4. (Note 1)

VBB

−

Internally generated reference voltage supply.

No Connect pin. The No Connect (NC) pin is electrically connected to the

die and MUST be left open.

CML Output

Noninverted differential output. Typically receiver terminated with 50 W

resistor to VCC.

CML Output

Inverted differential output. Typically receiver terminated with 50 W resistor

to VCC.

Negative supply voltage

5, 9, 12, 16

VCC

−

Positive supply voltage

−

Exposed pad (EP). EP on the package bottom is thermally connected to the

die for improved heat transfer out of the package. The pad is not electrically

connected to the die, but is recommended to be soldered to VEE on the

PC Board.

1. In the differential configuration when the input termination pins (VTD, VTD) are connected to a common termination voltage and if no signal

is applied on D/D input then the device will be susceptible to self−oscillation.
