3.0 V to 5.5 V, ±12 kV IEC ESD Protected, 500 kbps RS-485 Transceiver

Manufactured by:


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 ADM3061E/ADM3065E/ADM3066E feature a ¼ unit load input impedance, which allows up to 128 transceivers on a bus. The ADM3061E models offer all of the same features as the ADM3065E models, but at a low 500 kbps data rate suitable for operation over long cable runs.

The ADM3061E/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, an 8-lead, 3 mm × 3 mm MSOP, a 10-lead, 3 mm × 3 mm MSOP, 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 ADM3061E/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.

The EVAL-ADM3061EEBZ and EVAL-ADM3061EEB1Z allow quick and easy evaluation of the ADM3061E 50 Mbps RS-485 transceiver with standard SOIC and MSOP 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 V to 5 V range.

The EVAL-ADM3061EEBZ evaluation board has a footprint for the ADM3061EBRZ half-duplex RS-485 transceiver in an 8-lead SOIC package. The EVAL-ADM3061EEB1Z evaluation board has a footprint for a full duplex RS-485 transceiver in an 8-lead MSOP package.

Complete specifications for the ADM3061E device are provided in the ADM3061E data sheet and should be consulted in conjunction with user guide UG-1172 when using the evaluation board.
