Low-Power RS-485 Transceiver with Low-Voltage Interface

Exar Corp. recently announced the XR33202, which is a half-duplex, 20-Mbps RS-485 (TIA/EIA-485) transceiver optimized to operate over a wide 3-to-5.5-V supply voltage range. The transceiver includes an adjustable low voltage logic interface and features the industry’s lowest standby current of 3 µA (maximum), 0.05 µA (typical). The device’s wide operating voltage range, flexible logic interface, and low standby current make it ideal for battery-powered and multi-voltage systems.EX052_XR33202_Exar

The XR33202 exceeds the highest ESD rating of IEC 61000-4-2 Level 4. It also includes protection features such as hot swap glitch, overload and enhanced receiver fail-safe for open, shorted or terminated idle data lines.
