PIN FUNCTION DESCRIPTIONS
Pin Name
Pin Number
Description
VCC
1, 2
Positive Power Supply. Both pins should be connected to minimize inductance 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 inductance 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 out-
put for
DATA > DATA.
VH
18
Analog input that sets the voltage level of a Logic 1 of the driver. Determines the driver out-
put for DATA >
DATA.
VOUT
5
The Driver Output.
VHDCPL
3
Internal supply decoupling for the output stage. This pin is connected to VCC through a
39 nF (minimum) capacitor.
VLDCPL
7
Internal supply decoupling for the output stage. This pin is connected to VEE through a
39 nF (minimum) capacitor.
INH,
INH
10, 11
Differential inputs that control the high impedance state of the driver. When INH >
INH, the
driver goes into a high impedance state.
DATA,
DATA
13, 12
Differential inputs that determine the high and low state of the driver. Driver output is high
for DATA >
DATA.
TVCC
19
Temperature Sensor Startup Pin. This pin should be connected to VCC.
THERM
20
Temperature sensor output pin. A resistor (10 k
Ω) should be connected between THERM
and VCC. The approximate die temperature can be determined by measuring the current
through the resistor. The typical scale factor is 1
µA/K.
