PIN FUNCTION DESCRIPTIONS
Pin Functional Description
Positive Power Supply. Both pins
should be connected to minimize in-
ductance and allow maximum speed of
operation. V
GND with a low inductance 0.1 F
capacitor.
Negative Power Supply. Both pins
should be connected to keep the induc-
tance down and allow maximum speed
of operation. V
to GND with a low inductance 0.1 F
capacitor.
connected to the circuit board’s ground
plane at the pins.
Analog Input that sets the voltage level
of a Logic 0 of the driver. Determines
the driver output for DATA > DATA.
Analog input that sets the voltage level
of a Logic 1 of the driver. Determines
the driver output for DATA > DATA.
The Driver Output. The nominal out-
put impedance is 50 .
Internal supply decoupling for the
output stage. This pin is connected
to V
capacitors.
Internal supply decoupling for the
output stage. This pin is connected
to V
capacitors.
high impedance state of the driver.
When INH > INH, the driver goes into
a high impedance state.
ECL compatible inputs that determines
the high and low state of the driver.
Driver output is high for DATA >
DATA.
Temperature Sensor Start-Up Pin. This
pin should be connected to V
Temperature Sensor Output Pin. A
resistor (10K) should be connected
between THERM and V
proximate die temperature can be de-
termined by measuring the current
through the resistor. The typical scale
factor is 1 A/K.
