Product Details

The ADM3065E is a 3.0 V to 5.5 V, IEC electrostatic discharge (ESD) protected RS-485 transceiver, allowing the device to withstand ±12 kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM3066E features a VIO logic supply pin allowing a flexible digital interface capable of operating as low as 1.62 V.

The ADM3065E/ADM3066E are suitable for high speed, 50 Mbps, bidirectional data communication on multipoint bus transmission lines. The ADM3065E/ADM3066E feature a ¼ unit load input impedance, which allows up to 128 transceivers on a bus.

The ADM3065E/ADM3066E 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 RS-485 transceivers are available in a number of space-saving packages, such as a 10-lead, 3 mm × 3 mm LFCSP package, an 8-lead, 3 mm × 3 mm MSOP package, a 10-lead, 3 mm × 3 mm MSOP package, and an 8-lead, narrow body SOIC package. Models with operating temperature ranges of −40°C to +125°C and −40°C to +85°C are available.

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/ADM3066E guarantee a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled.

Product Details

The EVAL-ADM3066EEBZ and EVAL-ADM3066EEB1Z allow quick and easy evaluation of the ADM3066E 50 Mbps RS-485 transceiver with standard MSOP and LFCSP footprints, respectively. The evaluation boards allow the input and output functions to be exercised without external components. Screw terminal blocks provide convenient connections for power and ground, digital input and output, and RS-485 signals. The evaluation boards can be powered by a standard configurable bench power supply within a 3.0 V to 5.5 V range.


The EVAL-ADM3066EEBZ evaluation board has a footprint for the ADM3066EBRMZ half duplex RS-485 transceiver in an 10-lead MSOP package. The EVAL-ADM3066EEB1Z evaluation board has a footprint for a half duplex RS-485 transceiver in an 10-lead LFCSP package.


Complete specifications for the ADM3066E device are provided in the ADM3066E data sheet and should be consulted in conjunction with user guide (UG-1131) when using the evaluation board.
