The ADM1085-ADM1088 are Simple Sequencing™ circuits which provide a time delay between the enabling of voltage regulators at power-up in multiple supply systems. When the output voltage of the first regulator reaches a preset threshold, a time delay is initiated before an enable signal allows subsequent regulators to power-up. Any number of these devices can be cascaded with regulators to allow sequencing of multiple power supplies.Threshold levels can be set with a pair of external resistors in a voltage divider configuration. By choosing appropriate resistor values, the threshold can be adjusted to monitor voltages as low as 0.6V. The ADM1086 and ADM1088 have push-pull output stages, with active-high (ENOUT) and active-low (ENOUT) logic outputs, respectively. Similarly, the ADM1085 has an active-high (ENOUT) logic output and the ADM1087 has an active-low (ENOUT) output. Both the ADM1085 and ADM1087 have open-drain output stages which can be pulled up to voltage levels as high as 22V through an external resistor. This level shifting property of the ADM1085 and ADM1087 ensures compatibility with enable input logic levels of different regulators and converters.All four models have a dedicated enable input pin which allows the output signal to the regulator to be controlled externally. This is an active-high input (ENIN) for the ADM1085 and ADM1086, and an active-low input (ENIN) for the ADM1087 and ADM1088. The Simple Sequencers™ are specified over the extended –40°C to +125°C temperature range, and with low current consumption of 15µA (typ) and 6-lead SC70 packaging, they are suitable for low power portable applications.

The ADM2483 differential bus transceiver is an integrated,galvanically isolated component designed for bidirectional datacommunication on balanced, multipoint bus transmission lines.It complies with ANSI EIA/TIA-485-A and ISO 8482: 1987(E).Using the iCoupler technology from Analog Devices, Inc., theADM2483 combines a 3-channel isolator, a three-state differentialline driver, and a differential input receiver into a single package.The logic side of the device is powered with either a 5 V or 3 Vsupply, and the bus side uses a 5 V supply only.The ADM2483 is slew-limited to reduce reflections withimproperly terminated transmission lines. The controlled slewrate limits the data rate to 500 kbps. The device’s input impedanceis 96 kΩ, allowing up to 256 transceivers on the bus. Its driverhas an active-high enable feature. The driver differential outputsand receiver differential inputs are connected internally to forma differential input/output (I/O) port.When the driver is disabled or when VDD1 or VDD2 = 0 V, thisimposes minimal loading on the bus. An active-high receiverdisable feature, which causes the receive output to enter a highimpedance state, is provided as well.The receiver inputs have a true fail-safe feature that ensures alogic-high receiver output level when the inputs are open orshorted. This guarantees that the receiver outputs are in aknown state before communication begins and at the pointwhen communication ends.Current limiting and thermal shutdown features protect againstoutput short circuits and bus contention situations that mightcause excessive power dissipation. The part is fully specifiedover the industrial temperature range and is available in a16-lead, wide body SOIC package.Applications Low power RS-485/RS-422 networks Isolated interfaces Building control networks Multipoint data transmission systems

The ADM307xE are 3.3 V, low power data transceivers with ±15 kV ESD protection suitable for full- and half-duplex communication on multipoint bus transmission lines. They are designed for balanced data transmission, and they comply with TIA/EIA standards: RS-485 and RS-422.The devices have a ⅛ unit load receiver input impedance, which allows up to 256 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or powered-down driver is tristated to avoid overloading the bus.The receiver inputs have a true fail-safe feature, which eliminates the need for external bias resistors and ensures a logic high output level when the inputs are open or shorted. This guarantees that the receiver outputs are in a known state before communication begins and when communication ceases.Applications Power/energy metering Industrial control Lighting systems Telecommunications Security systems Instrumentation
