Analog Devices Inc. ADM306x Interface RS-485 Transceivers

Analog Devices Inc. ADM306x Interface RS-485 Transceivers are 3.0V to 5.5V, IEC electrostatic discharge (ESD) protected RS-485 transceivers. This allows the devices to withstand ±12kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM306x features a VIO logic supply pin that allows a flexible digital interface that operates as low as 1.62V. The ADM3065E/ADM3066E/ADM3067E/ADM3068E are suitable for high speed, 50Mbps, bi-directional data communication on multipoint bus transmission lines. The ADM3061E/ADM3062E/ADM3063E/ADM3064E feature a 1/4 unit load input impedance that allows up to 128 transceivers on a bus. The ADM3061E/ADM3062E/ADM3063E/ADM3064E models offer the same features as the ADM3065E/ADM3066E/ADM3067E/ADM3068E models at a low 500kbps data rate that is suitable for operation over long cable runs.

Analog Devices Inc. ADM3061E/ADM3062E/ADM3065E/ADM3066E are half-duplex RS-485 transceivers, fully compliant to the PROFIBUS® standard with increased 2.1V bus differential voltage at VCC ≥ 4.5V. The ADM3063E/ADM3064E/ADM3067E/ADM3068E are full-duplex RS-485 transceiver options. The RS-485 transceivers are available in several space-saving packages. These packages include the 10-lead, 3mm × 3mm lead-frame chip-scale package (LFCSP), the 8-lead or 10-lead, 3mm x 3mm mini small outline package (MSOP), and the 8-lead or 14-lead, narrow-body standard small-outline packages (SOIC_N). Models with operating temperature ranges of −40°C to +125°C and −40°C to +85°C are available.
