HS-3182 Data Sheet May 30, 2008 FN2963.3 ARINC 429 Bus Interface Line Driver Features Circuit RoHS/Pb-free Available for SBDIP Package (100% Gold The HS-3182 is a monolithic dielectric ally isolated bipolar Termination Finish) differential line driver designed to meet the specifications of TTL and CMOS Compatible Inputs ARINC 429. This device is intended to be used with a Adjustable Rise and Fall Times via Two External companion chip, HS-3282 CMOS ARINC Bus Interface Capacitors Circuit, which provides the data formatting and processor interface function. Input Programmable Output Differential Voltage via V REF All logic inputs are TTL and CMOS compatible. In addition to Operates at Data Rates Up to 100k Bits/s the DATA (A) and DATA (B) inputs, there are also inputs for Output Short Circuit Proof and Contains Overvoltage CLOCK and SYNC signals which are ANDd with the DATA Protection inputs. This feature enhances system performance and Outputs are Inhibited (0V) If DATA (A) and DATA (B) allows the HS-3182 to be used with devices other than the Inputs are Both in the Logic One State HS-3182. DATA (A) and DATA (B) Signals are ANDd with Clock Three power supplies are necessary to operate the HS-3182: and Sync Signals +V = +15V 10%, -V = -15V 10%, and V1 = 5V 5%. V is REF used to program the differential output voltage swing such that Full Military Temperature Range V (DIFF) = 2VREF. Typically, V = V1 = 5V 5%, but a OUT REF Pinouts separate power supply may be used for VREF which should not exceed 6V. HS-3182 (16 LD SBDIP) The driver output impedance is 75 20% at +25C. Driver TOP VIEW output rise and fall times are independently programmed V 1 16 V REF 1 through the use of two external capacitors connected to the CA GND 2 15 NC and CB inputs. Typical capacitor values are CA = CB = 75pF for SYNC 3 14 CLK high-speed operation (100kBPS), and CA = CB = 300pF for DATA (A) 4 13 DATA (B) low-speed operation (12kBPS to 14.5kBPS). The outputs are C 5 12 C protected against overvoltage and short circuit as shown in the A B A 6 11 B Block Diagram. The HS-3182 is designed to operate over an OUT OUT ambient temperature range of -55C to +125C, or -40C to -V 7 10 NC +85C. 9 +V GND 8 TABLE 1.
