The UM13082F is ?8V fault-protected, full-duplex, RS-422/RS-485 transceivers operating on a single 3V to 5.5V supply voltage. The device is available in 20Mbps. Bus interface pins are protected against overvoltage conditions during all modes of operation ensuring robust communication in rugged industrial environments.
The device also features integrated IEC ESD protection, eliminating the need for external system-level protection components. Extended ?5V 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 UM13082F is available in SOP8 and SOP14 packages. The device is designed for space-constrained applications and have extended ambient temperature range from -40癈 to 125癈.
