Description
The HS-3182 is a monolithic dielectrically isolated bipolar differ-
ential line driver designed to meet the specifications of ARINC
429. This Device is intended to be used with a companion chip,
HS-3282 CMOS ARINC Bus Interface Circuit, which provides
the data formatting and processor interface function.
All logic inputs are TTL and CMOS compatible. In addition to
the DATA (A) and DATA (B) inputs, there are also inputs for
CLOCK and SYNC signals which are AND'd with the DATA
inputs. This feature enhances system performance and allows
the HS-3182 to be used with devices other than the HS-3182.
Three power supplies are necessary to operate the
HS-3182: +V = +15V
10%, -V = -15V
10%, and V
1
= 5V
5%. V
REF
is used to program the differential output voltage
swing such that V
OUT
(DIFF) =
2V
REF
. Typically, V
REF
=
V
1
= 5V
5%, but a separate power supply may be used for
V
REF
which should not exceed 6V.
The driver output impedance is 75
20% at 25
o
C. Driver
output rise and fall times are independently programmed
through the use of two external capacitors connected to the
C
A
and C
B
inputs. Typical capacitor values are C
A
= C
B
=
75pF for high-speed operation (100KBPS), and C
A
= C
B
=
300pF for low-speed operation (12 to 14.5KBPS). The out-
puts are protected against over-voltage and short circuit as
shown in the Block Diagram. The HS-3182 is designed to
operate with a case temperature range of -55
o
C to +125
