Key Specifications

 
UM13082V series are ±18V fault-protected, half-duplex, RS-485 transceivers using a 1.65V to 5.5V supply for logic signal interface, and a 3V to 5.5V bus side supply. Bus interface pins are protected against overvoltage conditions during all modes of operation ensuring robust communication in rugged industrial environments.

UM13082V series are available in 20Mbps. All devices also feature integrated IEC ESD protection, eliminating the need for external system-level protection components. Extended ±15V input common-mode range ensures reliable data communication over longer cable run lengths and/or in the presence of large ground loop voltages. Enhanced 250mV receiver hysteresis provides high noise rejection. In addition, the receiver fail-safe feature provides a logic high when the bus inputs are open or shorted together.

UM13082V series are available in SOP8, MSOP8, DFN10 3.0×3.0 packages. All devices are designed for space-constrained applications.
