The ADM1486 is a differential line transceiver suitable for high speed bidirectional data communication on multipoint bus transmission lines. It is designed for balanced data transmission, complies with EIA Standards RS-485 and RS-422 and is recommended for PROFIBUS applications. The part contains a differential line driver and a differential line receiver. Both the driver and the receiver may be enabled independently. When disabled or with power off, the driver outputs are tristated.

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

Operating from a single supply as low as +2.7 V, the ADM3307E is a five-driver/three-receiver serial port transceiver, and fully meets full EIA-232 standards. It features an on-board, charge pump dc-to-dc converter, which eliminates the need for dual power supplies. This dc-to-dc converter also contains a voltage tripler and voltage inverter for internally generating positive and negative supplies from the power supply. It operates in Green Idle Mode, where the charge pump oscillator is gated on and off to maintain output voltage to +/-7.25 V, regardless of the load conditions. It has the added benefit of having +15kV ESD protection on both the RS-232 I/O pins and the TTL pins, making it ideal for harsh environments. It also operates at speeds of up to 1Mbps. The ADM3307E is available in a 28-pin TSSOP package as well as a space-saving 32-pin LFCSP package.APPLICATIONS Mobile phone handsets/data cables Laptop and notebook computers Printers Peripherals Modems PDAs/Hand-Held Devices/Palmtop Computers

The ADM3311E is a three driver/five receiver product designed to fully meet the EIA-232 standard while operating with a single +2.7 to 3.6V power supply. The devices feature an on-chip DC to DC converter, eliminating the need for dual power supplies. This DC-DC converter contains a voltage tripler and voltage inverter which internally generates a regulated ±7.5V from the input 3V power supply. An internal voltage monitoring circuit continually adjusts the oscillator frequency to maintain the desired output voltage levels. In an unloaded state, the oscillator idles at a minimum frequency (Green-Idle Mode™) thereby minimizing the power consumption. This makes these products ideal for battery powered portable devices.APPLICATIONS Mobile phone handsets/data cables Laptop and notebook computers Printers Peripherals Modems PDAs/Hand-Held Devices/Palmtop Computers
