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.
"The adjustable low voltage interface included in the XR33202 simplifies integration of the transceiver in low voltage and multi-voltage systems," said Dale Wedel, Exar's vice president, high performance analog products.
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.
