HS-3182 March 1997 ARINC 429 Bus Interface Line Driver Circuit Description The HS-3182 is a monolithic dielectrically isolated bipolar differential 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 V1 = 5V ± 5%.
