The ADM3065E-EP/ADM3066E-EP/ADM3067E-EP are 3.0 V to 5.5 V, IEC electrostatic discharge (ESD) protected RS-485 transceivers, allowing the devices to withstand ±12 kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM3066E-EP features a VIO logic supply pin allowing a flexible digital interface capable of operating as low as 1.62 V. The ADM3065E-EP/ADM3066E-EP/ADM3067E-EP are suitable for high speed, 50 Mbps, bidirectional data communication on multipoint bus transmission lines. The ADM3065E-EP/ ADM3066E-EP/ADM3067E-EP feature a one-fourth unit load input impedance, which allows up to 128 transceivers on a bus. The ADM3065E-EP/ADM3066E-EP are half-duplex RS-485 transceivers, fully compliant to the PROFIBUS® standard with increased 2.1 V bus differential voltage at VCC ≥ 4.5 V. The ADM3067E-EP is a full duplex RS-485 transceiver option. The RS-485 transceivers are available in a number of spacesaving packages, such asthe 8-lead or 10-lead, 3 mm × 3 mm MSOP; and the 8-lead or 14-lead, narrow-body SOIC packages.

Excessive power dissipation caused by bus contention or by output shorting is prevented by a thermal shutdown circuit. If, during fault conditions, a significant temperature increase is detected in the internal driver circuitry, this feature forces the driver output into a high impedance state. The ADM3065E-EP/ADM3066E-EP/ADM3067E-EP guarantee a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled. Table 1 presents an overview of the ADM3065E-EP/ ADM3066E-EP/ADM3067E-EP data rate capability across temperature, power supply, and package options. Refer to the Ordering Guide for model numbering. Additional application and technical information can be found in the ADM3065E/ADM3066E/ADM3067E data sheet.
