The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E are 3.0 V to5.5 V, IEC electrostatic discharge (ESD) protected RS-485transceivers, allowing the devices to withstand ±12 kV contactdischarges on the transceiver bus pins without latch-up ordamage. The ADM3062E/ADM3064E/ADM3066E/ADM3068Efeature a VIO logic supply pin that allows a flexible digital interfacecapable of operating as low as 1.62 V.
The ADM3065E/ADM3066E/ADM3067E/ADM3068E aresuitable for high speed, 50 Mbps, bidirectional data communication on multipoint bus transmission lines. The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E feature a 1/4 unit load inputimpedance that allows up to 128 transceivers on a bus. TheADM3061E/ADM3062E/ADM3063E/ADM3064E models offerall of the same features as the ADM3065E/ADM3066E/ADM3067E/ADM3068E models at a low 500 kbps data rate thatis suitable for operation over long cable runs.
The ADM3061E/ADM3062E/ADM3065E/ADM3066EACPZ are halfduplex RS-485 transceivers, fully compliant to the PROFIBUS®standard with increased 2.1 V bus differential voltage at VCC ≥4.5 V. The ADM3063E/ADM3064E/ADM3067E/ADM3068Eare full duplex RS-485 transceiver options.
The RS-485 transceivers are available in a number of spacesaving packages, including the 10-lead, 3 mm × 3 mm lead framechip-scale package (LFCSP), the 8-lead or 10-lead, 3 mm × 3 mmmini 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°Cand −40°C to +85°C are available.
Excessive power dissipation caused by bus contention or byoutput shorting is prevented by a thermal shutdown circuit. If asignificant temperature increase is detected in the internal drivercircuitry during fault conditions, this feature forces the driveroutput into a high impedance state.
The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E guarantee alogic high receiver output when the receiver inputs are shorted,open, or connected to a terminated transmission line with alldrivers disabled.
Table 2 presents an overview of the ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E data rate capability across temperature, power supply,and package options. Refer to the Ordering Guide section formodel numbering.
