Positive Power Supply. Both pins
should be connected to minimize in-

should be decoupled to
GND with a low inductance 0.1

capacitor.
Negative Power Supply. Both pins
should be connected to keep the induc-
tance down and allow maximum speed
of operation. V

Device Ground. These pins should be
connected to the circuit board’s ground
plane at the pins.

The Driver Output. The nominal out-
put impedance is 50

Internal supply decoupling for the
output stage. This pin is connected
to V

ECL compatible input that control the
high impedance state of the driver.
When INH >

a high impedance state.
ECL compatible inputs that determines
the high and low state of the driver.

Temperature Sensor Start-Up Pin. This
pin should be connected to V
CC
.
Temperature Sensor Output Pin. A
resistor (10K) should be connected
between THERM and V
CC
. The ap-
proximate die temperature can be de-
termined by measuring the current
through the resistor. The typical scale
factor is 1
