Noninverted Differential Output.
11
Q1
RSECL Output
Inverted Differential Output.
12
VCC
Positive Supply. All VCC Pins must be Externally Connected to Power Supply to
Guarantee Proper Operation.
13
OLS
(Note 2)
Input
Input Pin for Output Level Select (OLS) See Table 3.
14
Q0
RSECL Output
Noninverted Differential Output Typically Terminated with 50
W Resistor to
VTT = VCC − 2.0 V.
15
Q0
RSECL Output
Inverted Differential Output Typically Terminated with 50
W Resistor to
VTT = VCC − 2.0 V.
16
VCC
Positive Supply. All VCC Pins must be Externally Connected to Power Supply to
Guarantee Proper Operation.
EP
Exposed Pad. The thermally exposed pad on package bottom (see case drawing)
must be attached to a heat−sinking conduit.
1. In the differential configuration when the input termination pins (VTD0, VTD1) are connected to a common termination voltage, and if no signal
is applied then the device will be susceptible to self−oscillation.
2. When an output level of 400 mV is desired and VCC − VEE > 3.0 V, 2 kW resistor should be connected from OLS pin to VEE.
