ISO3088DW

ISO3088DW Description

The ISO3088DW from Texas Instruments is a high-performance, galvanically isolated RS-422/RS-485 transceiver designed for robust industrial communication. Housed in a 16-pin SOIC package, it integrates 2 drivers and 2 receivers with reinforced isolation, supporting half-duplex communication at data rates up to 20Mbps. Operating across dual supply voltages (3.15V–5.5V for logic side, 4.5V–5.5V for bus side), it ensures compatibility with diverse system architectures. The device meets ROHS3 and REACH compliance, making it suitable for environmentally conscious designs. Its 30mV receiver hysteresis enhances noise immunity, critical for electrically noisy environments.

ISO3088DW Features

• Isolated Communication: Reinforced isolation (2,500Vrms) protects sensitive electronics from ground loops and high-voltage transients.
• Wide Supply Range: Dual-voltage operation (3.15V–5.5V logic, 4.5V–5.5V bus) accommodates mixed-voltage systems.
• High-Speed Performance: Supports 20Mbps data rates, ideal for time-sensitive industrial networks.
• Robust Noise Immunity: 30mV hysteresis minimizes false signaling in noisy environments.
• Compliance & Reliability: ROHS3, REACH, and EAR99 certifications ensure global usability.
• Last-Time-Buy Status: Engineers should consider stock availability for legacy system maintenance.

ISO3088DW Applications

• Industrial Automation: Isolated RS-485 networks in PLCs, motor drives, and factory control systems.
• HVAC & Building Control: Long-distance communication with noise immunity for sensors and actuators.
• Energy Infrastructure: Isolated data links in smart meters, inverters, and grid monitoring equipment.
• Medical Devices: Safe signal transmission in patient-connected equipment requiring galvanic isolation.
• Transportation Systems: Robust communication in avionics, railway signaling, and automotive diagnostics.

Conclusion of ISO3088DW

The ISO3088DW stands out for its high-speed isolated communication, dual-voltage flexibility, and industrial-grade robustness. While marked as Last Time Buy, it remains a reliable choice for legacy upgrades or designs requiring proven isolation technology. Its 30mV hysteresis and 20Mbps capability make it superior in noisy, high-speed applications compared to non-isolated or slower alternatives. Engineers should evaluate stock availability and consider migration paths for future-proofing designs.
