RM3182A
PRODUCT SPECIFICATION

Applications
Heat Sinking /Air Flow and Short Circuit
Protection
The user application will determine if and how much heat
sinking/air flow will be required for the RM3182A.
Consideration must be given to ambient temperature, load
conditions and output voltage swing. In addition, power
consumption increases with increased operating frequency.
Use the numbers given in the Thermal Characteristics Table
to determine that the maximum allowable junction tempera-
ture of 175
°
C is not exceeded.
Outputs Out A and Out B are short circuit protected by the
internal 37.5
W
back termination resistors. During a short
circuit of the output to either power supply or ground, the
device must be able to dissipate the generated heat. For
example, if the output is shorted to ground and V
CC
= +15V,
the device must dissipate 15V x 0.165A = 2.5W. An appro-
priate heat sink is required in this situation.
Note that the Amp A and Amp B outputs are not short circuit
protected. Shorting these pins to either power supply or
ground will cause failure of the device. An added external
resistor will protect the circuit by limiting the current.
Power Supply Considerations
Three power supplies are required to operate the RM3182A
in a typical ARINC 429 bus application: +15V for V
CC
,
-15V for V
EE
, and +5V for both V
REF
and V
LOGIC
. The dif-
ferential output swing of the RM3182A is equal to 2 x V
REF
.
Using +5V gives a differential output swing of 10V.
If a different output voltage swing is required, an additional
power supply is needed to set V
LOGIC
.
Each power supply pin should be decoupled to ground using
a high quality 10
m
F tantalum capacitor. This is especially
true when driving a large capacitive or resistive loads. The
decoupling capacitors should be located as close to the
device pins as possible to eliminate the wiring inductance.
Typical ARINC 429 Application
Figure 5 shows typical switching waveform for the
RM3182A in any configuration.
Figure 6 depicts connections for a ARINC 429 high speed
bus driver application. This circuit shows the complete
configuration for a 100 Kbits/sec, 10V differential output
swing using the terminated output pins.
