Positive Power Supply. Both pins should be connected to minimize inductance and allow
maximum speed of operation. V
CC
should be decoupled to GND with a low inductance
0.1

F capacitor.
Negative Power Supply. Both pins should be connected to keep the inductance down and
allow maximum speed of operation. V
EE
should be decoupled to GND with a low inductance
0.1

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

The Driver Output.
Internal supply decoupling for the output stage. This pin is connected to V
CC
through a
39 nF (minimum) capacitor.
Internal supply decoupling for the output stage. This pin is connected to V
EE
through a
39 nF (minimum) capacitor.
Differential inputs that control the high impedance state of the driver. When INH >
INH
, the
driver goes into a high impedance state.
Differential inputs that determine the high and low state of the driver. Driver output is high

.
Temperature Sensor Startup Pin. This pin should be connected to V
CC
.
Temperature sensor output pin. A resistor (10 k
) should be connected between THERM
and V
CC
. The approximate die temperature can be determined by measuring the current
through the resistor. The typical scale factor is 1
μ
A/K.
