The MAX14945EWE+ from Analog Devices is a high-performance, isolated RS-485/RS-422 transceiver designed for robust communication in demanding environments. It provides 2750VRMS of galvanic isolation for 60 seconds, effectively breaking ground loops and reducing noise caused by potential differences between ports. This isolation is achieved through integrated high-voltage capacitors.
This transceiver supports data rates up to 500kbps and features a receiver that is 1/8-unit load, allowing for up to 256 transceivers on a common bus. Integrated true fail-safe circuitry ensures a logic-high output when inputs are shorted or open, while undervoltage lockout protects the driver when power supplies are below functional levels. The device also includes ±30kV ESD protection on driver outputs and receiver inputs, and withstands ±10kV surge per IEC 61000-4-5.
The MAX14945EWE+ operates over a temperature range of -40°C to +85°C and is available in a 16-pin wide SOIC package suitable for surface mounting. Its integrated LDO for cable-side power and thermal shutdown safety features contribute to its reliability in applications such as industrial automation equipment, programmable logic controllers, HVAC systems, and power meters.
