PIN FUNCTION DESCRIPTIONS
Pin
Pin
Name
Number
Pin Functional Description
VCC
1, 2
Positive Power Supply. Both pins
should be connected to minimize in-
ductance and allow maximum speed of
operation. VCC should be decoupled to
GND with a low inductance 0.1
µF
capacitor.
VEE
8, 9
Negative Power Supply. Both pins
should be connected to keep the induc-
tance down and allow maximum speed
of operation. VEE should be decoupled
to GND with a low inductance 0.1
µF
capacitor.
GND
4, 6, 14,
16, 17
Device Ground. These pins should be
connected to the circuit board’s ground
plane at the pins.
VL
15
Analog Input that sets the voltage level
of a Logic 0 of the driver. Determines
the driver output for
DATA > DATA.
VH
18
Analog input that sets the voltage level
of a Logic 1 of the driver. Determines
the driver output for DATA >
DATA.
VOUT
5
The Driver Output. The nominal out-
put impedance is 50
Ω.
VHDCPL
3
Internal supply decoupling for the
output stage. This pin is connected
to VCC through a 39 nF minimum
capacitors.
VLDCPL
7
Internal supply decoupling for the
output stage. This pin is connected
to VEE through a 39 nF minimum
capacitors.
INH,
INH 10, 11
ECL compatible input that control the
high impedance state of the driver.
When INH >
INH, the driver goes into
a high impedance state.
DATA,
13, 12
ECL compatible inputs that determines
DATA
the high and low state of the driver.
Driver output is high for DATA >
DATA.
TVCC
19
Temperature Sensor Start-Up Pin. This
pin should be connected to VCC.
THERM
20
Temperature Sensor Output Pin. A
resistor (10K) should be connected
between THERM and VCC. The ap-
proximate die temperature can be de-
termined by measuring the current
through the resistor. The typical scale
factor is 1
µA/K.
