DD-03182 S ERIES
ARINC 429 LINE DRIV ER
DESCRIPTION
The DD-03182 device is a line driver
chip that transmits data on the serial
data bus in accordance with the
“ARINC Specification 429 Mark 33
Digital Information Transfer System”
(ARINC 429). This device can be used
with DDC’s DD-03296 discrete-to-digi-
tal device, in conjunction with the DD-
03282 transceiver chip or the DD-
00429 microprocessor interface.
The line driver receives TTL informa-
tion on the Data
A
/Data
B
input pins
and transmits it out on the A

/B
OUT
output pins. The output voltage level
is programmable via the V
REF
input
pin. The output pins are also protect-
ed against short circuits from aircraft
power.The slew rate of the DD-03182
can be programmed for either High
(100 kbit) or Low (12.5 kbit) speed via
two external timing capacitors con-
nected to the C
A
/C
B
input pins.
APPLICATIONS
The DD-03182 can be used for many
different applications ranging from
flight critical to nonessential. Surface
mount, DIP and PLCC package con-
figurations are available. Military tem-
perature range is also available if
required.
