The UM13085 is ?8V fault-protected, half-duplex, RS-485 transceivers operating on a single 3V to 5.5V supply voltage. Bus interface pins are protected against overvoltage conditions during all modes of operation ensuring robust communication in rugged industrial environments.
The UM13085 is available in 50Mbps. Extended ±15V 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 ensures high noise rejection. In addition, the receiver fail-safe feature guarantees a logic high when the inputs are open or shorted together.
The UM13085 is available in SOP8, MSOP8 and DFN8 3.0?.0 packages for space-constrained applications. The device is characterized over ambient free-air temperatures from -40°C to 125°C.
