HS-3182
March 1997
ARINC 429 Bus Interface Line Driver Circuit
Description
The HS-3182 is a monolithic dielectrically isolated bipolar differ-
ential line driver designed to meet the speci鏗乧ations 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鈥檇 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

output rise and fall times are independently programmed
through the use of two external capacitors connected to the

shown in the Block Diagram. The HS-3182 is designed to
operate with a case temperature range of -55
