What are the key features of ISO1176DWRG4?
- Isolated RS-485/RS-422 single transceiver with EIA-485 and TIA-485 standard compliance for robust industrial communication
- Differential Schmitt trigger input architecture provides superior noise immunity on long cable runs in harsh EMI environments
- 1.8V minimum differential output swing in a 16-pin SOIC package enables reliable signal integrity over extended transmission lines
What is ISO1176DWRG4 used for?
The ISO1176DWRG4 is designed for isolated RS-485 and RS-422 serial communication in industrial automation, building control systems, and fieldbus networks where galvanic isolation between the bus and controller is required. Its isolated architecture protects microcontrollers and host systems from ground loops, voltage surges, and common-mode noise prevalent in factory floor environments. The device is also suitable for isolated PROFIBUS, Modbus, and DMX512 interfaces in lighting control, motor drives, and distributed sensor networks.

Frequently Asked Questions
What communication standard does the ISO1176DWRG4 support?
The ISO1176DWRG4 is compliant with EIA-485 and TIA-485 standards for half-duplex RS-485 differential communication. It supports single-driver, single-receiver operation making it suitable for multi-drop bus topologies with up to 32 unit loads, commonly used in industrial Modbus and PROFIBUS applications.
What is the minimum output voltage swing of the ISO1176DWRG4?
The ISO1176DWRG4 provides a minimum differential output swing of 1.8V, which exceeds the EIA-485 minimum specification of 1.5V. This ensures reliable signal reception even at the end of long cable runs or in environments with significant common-mode noise or signal attenuation.
What package does the ISO1176DWRG4 use?
The ISO1176DWRG4 is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package, JESD-30 code R-PDSO-G16. This through-hole-friendly surface-mount package offers wide creepage distances appropriate for isolated transceiver applications and is widely supported in standard PCB assembly processes.
Is the ISO1176DWRG4 suitable for hazardous or noisy industrial environments?
Yes, the ISO1176DWRG4 features differential Schmitt trigger inputs that provide built-in hysteresis to reject noise and glitches on the bus line. The integrated isolation barrier further protects connected circuits from high-voltage transients, ground potential differences, and ESD events common in industrial and process control environments.
