ADM3066EACPZ

The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ ADM3066E/ADM3067E/ADM3068E are 3.0 V to 5.5 V, IEC electrostatic discharge (ESD) protected RS-485 transceivers, allowing the devices to withstand ±12 kV contact discharges on the transceiver bus pins without latch-up or damage. The ADM3062E/ADM3064E/ ADM3066E/ADM3068E feature a V10 logic supply pin that allows a flexible digital interface capable of operating as low as 1.62 V. The ADM3065E/ADM3066E/ADM3067E/ADM3068E are suitable for high speed, 50 Mbps, bidirectional data communication on multipoint bus transmission lines. ADM3061E/ADM3062E/ADM3063E/ ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E feature a 1/4 unit load input impedance that allows up to 128 transceivers on a bus. The ADM3061E/ADM3062E/ADM3063E/ ADM3064E models offer all of the same features as the ADM3065E/ADM3066E/ ADM3067E/ADM3068E models at a low 500 kbps data rate that is suitable for operation over long cable runs. The ADM3061E/ADM3062E/ADM3065E/ADM3066E are half-duplex RS-485 transceivers, fully compliant to the PROFIBUS standard with increased 2.1 V bus differential voltage at VCC ≥4.5V. The ADM3063E/ADM3064E/ADM3067E/ADM3068E are full duplex RS-485 transceiver options. The RS-485 transceivers are available in a number of space-saving packages, including the 10-lead, 3 mm x 3 mm lead frame chip-scale package (LFCSP); the 8‑lead or 10-lead, 3 mm x 3 mm 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℃ to +125℃ and -40℃ to +85℃ are available. 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 ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ ADM3066E/ADM3067E/ADM3068E guarantee a logic high receiver output when the receiver inputs are shorted, open, or connected to a terminated transmission line with all drivers disabled.
