HS-3182 is a bipolar differential line driver chip from Intersil, which is designed to meet the specifications of ARINC 429 bus. It is intended to be used with HS-3282 CMOS ARINC Bus Interface Circuit to provide data formatting and processor interface function.
The HS-3182 is a monolithic, dielectric‑isolated bipolar differential line driver designed for ARINC‑429 bus applications. It works with the companion HS‑3282 CMOS ARINC bus interface circuit and accepts TTL and CMOS compatible inputs, with DATA signals AND‑ed with CLOCK and SYNC.
Key features include RoHS‑compliant SBDIP packaging, programmable output differential voltage, adjustable rise/fall times via external capacitors, short‑circuit and over‑voltage protection, and operation over a military temperature range. Detailed pinouts, ordering information, and mechanical drawings are provided.
| Supply Voltage +V | +15 V ±10 % |
|---|---|
| Supply Voltage -V | -15 V ±10 % |
| Supply Voltage V1 (VREF) | 5 V ±5 % |
| Output Impedance | 75 Ω |
| Input Logic High Voltage | ≥ 2.0 V |
| Operating Temperature Range (HS‑3182‑8) | -55 °C to +125 °C |
