ADM3067ETRZ-EP

ADM3067ETRZ-EP is an IEC electrostatic discharge (ESD) protected RS-485 transceiver allowing the device to withstand ±12kV contact discharges on the transceiver bus pins without latch-up or damage. It features a VIO logic supply pin that allows for a flexible digital interface capable of operating as low as 1.62V. It features a one-fourth unit load input impedance, which allows up to 128 transceivers on a bus. The ADM3067E-EP is a full duplex RS-485 transceiver option. Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. If a significant temperature increase is detected in the internal driver circuitry during fault conditions, this feature forces the driver output into a high-impedance state. Application includes industrial fieldbuses, process control, building automation, PROFIBUS networks, motor control servo drives and encoders.
