Lowest Power RS-485 Transceiver from Exar Includes Low Voltage Interface and Features <3 uA Standby Current

Exar XR33202

Exar Corporation announces the XR33202, a half-duplex, 20 Mbps RS-485 (TIA/EIA-485) transceiver optimized to operate over a wide 3 V 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 (max), 0.05 µA (typ). The device's wide operating voltage range, flexible logic interface, and low standby current make it ideal for battery-powered and multi-voltage systems.
