Exar – XR33202: Lowest Power RS-485 Transceiver with 1.65V to 5.5V I/O Interface



The XR33202 is a high performance TIA-485/TIA-422 transceiver designed to meet the increasing system requirements found in today’s portable/handheld, process control and industrial equipment. The device operates at a maximum data rate of 20Mbps and features a 1.65V to 5.5V I/O logic supply, simplifying multi-voltage system interfacing requirements. The receiver includes full fail-safe circuitry, guaranteeing a logic high receiver output when the receiver inputs are open, shorted or undriven. The XR33202 receiver input impedance is at least 96kΩ (1/8 unit load), allowing more than 256 devices on the bus.
