Introduction
CA-IS3082Cx is an enhanced isolation half-duplex RS-485 transceiver with a high electrical isolation rating, meeting the stringent requirements of industrial applications. The logic input and output buffers within this series are isolated via a silicon dioxide (SiO₂) insulation barrier, capable of withstanding electrical isolation up to 5000Vₚ₋ₚ (1 minute) and providing a typical CMTI performance of ±150kV/μs. The insulation barrier blocks ground loops between the logic side and bus side, helping to reduce inter-port interference caused by high ground potential differences and ensuring correct data transmission.
CA-IS3082Cx devices support multi-node data communication buses with a maximum communication rate of 500kbps and allow up to 256 transceivers on the same bus. CA-IS3082Cx is a half-duplex transceiver whose transmit/receive state is controlled via the receiver enable and driver enable pins, preventing bus contention.
CA-IS3082Cx devices are available in a 16-pin wide-body SOIC package with a pinout compatible with mainstream isolated RS-485 transceivers, supporting an operating temperature range of -40℃ to 125℃.
The CA-IS3082Cx enhanced isolation half-duplex RS-485 transceiver provides electrical isolation of up to 5kVₚ₋ₚ between the bus side and controller side (logic side). These devices feature ±150kV/μs CMTI and support a data rate of 500kbps. This series enables reliable data transmission in noisy environments and is suitable for a wide range of industrial applications including motor drives, PLC communication modules, and HVAC systems. The transceivers employ two mechanisms to prevent excessive power consumption during bus faults or bus contention: first, the driver incorporates current-limiting protection — in the event of an output short circuit within the allowable common-mode voltage range, the driver output is current-limited; second, thermal shutdown protection disables the driver once the device junction temperature is detected to exceed the thermal shutdown threshold.
Features
- RS-485 transceiver meeting or exceeding TIA/EIA-485A standard data rate: 500kbps
- 1/8 unit load (supports up to 256 bus nodes)
- Logic-side supply voltage range: 3V to 5.5V
- Bus-side supply voltage range: 3V to 5.5V
- Bus common-mode operating range: -7V to +12V
- High common-mode transient immunity: ±150kV/μs (typical)
- Bus A/B pin ESD protection level: ±20kV (HBM)
- Current-limiting driver with thermal shutdown
- Open-circuit, short-circuit, and idle bus failsafe protection
- Wide operating temperature range: -40℃ to 125℃
- 16-pin wide-body SOIC package, pin-compatible with mainstream isolated RS-485 transceivers
- Isolation barrier lifetime greater than 40 years at rated operating voltage
- Excellent isolation performance (certification in progress): compliant with UL 1577, 1-minute 5kVₚ₋ₚ isolation withstand voltage
- 7070Vₚ₋ₚ V₁₀ₜₘ per DIN EN IEC 60747-17 (VDE 0884-17):2021-10
- CQC certification per GB4943.1-2022
- TUV certification
