XR33152/XR33155/XR33156/XR33158 60V Fault Tolerant 3.0V to 5.5V RS-485/RS-422 Transceivers Description FEATURES The XR33152, XR33155, XR33156 and XR33158 (XR3315x) family of 3.0V to 5.5V operation high performance RS-485/RS-422 devices are designed for improved 60V fault tolerance on analog bus pins Extended 25V common mode operation performance in noisy industrial environments and increased tolerance Robust ESD protection: to system faults. 15kV HBM (bus pins) The analog bus pins can withstand direct shorts up to 60V and are 4kV HBM (non-bus pins) protected against ESD events up to 15kV HBM. An extended 25V 1.65V to 5.5V logic Interface VL pin common mode operating range allows for more reliable operation in (full-duplex package option) Invert control to correct for reversed noisy environments. bus pins The XR3315x receivers include full fail-safe circuitry, guaranteeing a Enhanced receiver fail-safe protection for logic high receiver output when the receiver inputs are open, shorted open, shorted or terminated but idle or undriven. The XR33152/55 receiver input impedance is at least data lines 120k (1/10 unit load), allowing more than 320 devices on the bus. Hot swap glitch protection on DE and RE pins The XR33156/58 receiver input impedance is at least 30k (1/2.5 Driver short-circuit current limit and unit load), allowing more than 80 devices on the bus. thermal shutdown for overload protection The drivers are protected by short circuit detection as well as thermal Reduced unit loads allows up to 320 shutdown and maintain high impedance in shutdown or when powered devices on bus off. The XR33152 driver is slew limited for reduced EMI and error-free Industry standard 8-pin and 14-pin communication over long or unterminated data cables. NSOIC packages -40C to 85C and -40C to 105C ambient The XR3315x family of high performance RS-485/RS-422 devices are operating temperature ranges designed for improved performance in noisy industrial environments and increased tolerance to system faults. APPLICATIONS Industrial control networks The devices with DE and RE pins include hot swap circuitry to prevent HVAC networks false transitions on the bus during power up or live insertion and can Building and process automation enter a 1nA low current shutdown mode for extreme power savings.
