±80V Fault-Protected, Full-Duplex RS-485 Transceiver Eliminates External Protection Circuitry 29/8/2008

Maxim Integrated Products introduces the MAX13448E ±80V fault-protected, full-duplex RS-485 transceiver. Capable of withstanding shorts up to ±80V on the RS-485 interface pins, this device eliminates the need for external fault-protection circuitry, typically polyswitch limiters and zener diodes. The transceiver prevents data from being transmitted during a fault condition, and then resumes normal operation after the fault condition has been removed. This integrated fault protection is useful in architectures such as USB and CAN in which power ...
