Analog Devices Inc. ADM3064E Full-Duplex RS-485 Transceiver

Analog Devices Inc. ADM3064E Full-Duplex RS-485 Transceiver features IEC Electrostatic Discharge (ESD) protection, allowing this device to withstand ±12kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM3064E features a VIO logic supply pin that allows a flexible digital interface capable of operating as low as 1.62V.

The ADM3064E features a 1/4 unit load input impedance that allows up to 128 transceivers on a bus. This device operates at a low 500kbps data rate suitable for operation over long cable runs. 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. The ADM3064E Transceiver guarantees a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled.
