The ADuM1250 /?ADuM1251 are hot swappable digital isolators with non-latching, bidirectional communication channels compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers.The ADuM1250 provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM1251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.Both the ADuM1250 and ADuM1251 contain hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus.These isolators are based on iCoupler? chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages as compared to optocouplers. With the ADuM1250 / ADuM1251, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.APPLICATIONS Isolated I2C, SMBus, or PMBus interfaces Multilevel I2C interfaces Power supplies Networking Power over Ethernet Hybrid electric vehicle battery management

The ADuM160N/ADuM161N/ADuM162N/ADuM163N are 6-channel digital isolators based on Analog Devices, Inc., iCoupler? technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 4.5 ns at 5 V operation. Channel to channel matching of propagation delay is tight at 4.0 ns maximum.The ADuM160N/ADuM161N/ADuM162N/ADuM163N data channels are independent and are available in a variety of configurations with a withstand voltage rating of 3.0 kV rms (see the Ordering Guide).

The ADuM3154 is an SPIsolator? digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four slave devices. Based on the Analog Devices, Inc., iCoupler? chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and SS SPI bus signals support SPI clock rates of up to 17 MHz.The ADuM3154 isolator also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. When a target slave is selected, the slave select signal propagates to the desired output with low propagation delay, allowing tight timing control. The isolated SSx is addressed through a 250 kbps low speed, 2-channel address bus, allowing the target slave device to be changed in as little as 2.5 ?s.Applications Industrial programmable logic controllers (PLCs) Sensor isolation

The ADuM3480 / ADuM3481 / ADuM3482 are quad-channel digital isolators based on the Analog Devices, Inc.,iCoupler? technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. With typical propagation delay reduced to 25 ns, pulse width distortion is also halved.The four channels of the ADuM3480 / ADuM3481 / ADuM3482 are available in a variety of channel configurations with two data rate grades up to 25 Mbps (see the Ordering Guide section). All models use separate core and I/O power supplies. The core operates between 3.0 V and 5.5 V, whereas the I/O supply can range from 1.8 V to 5.5 V. If operation is required within the range of the core supply, the two supplies can be tied together to allow single-supply operation. When the I/O must interface with logic levels that are different from the core supply voltage, then the I/O supply can be operated independently of the core supply over a wider range. The minimum I/O supply voltage is 1.8 V, allowing compatibility with low voltage logic. Both core and I/O supplies are required for proper operation.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation Industrial field bus isolation

The ADP5587 is an I/O port expander and keypad matrix designed for QWERTY type phones that require a large keypad matrix and expanded I/O lines. I/O expander ICs are used in mobile platforms as a solution to the limited number of GPIOs available in the main processor.In its small 2 mm ? 2 mm package, the ADP5587 contains?enough power to handle all key scanning and decoding and to flag the processor of key presses and releases via the I2C interface and interrupt. The ADP5587 frees the main microprocessor from the need to monitor the keypad, thereby?minimizing current drain and increasing processor bandwidth. The ADP5587 is also equipped with a buffer/FIFO and key?event counter to handle and keep track of up to 10 unprocessed key or GPI events with overflow wrap and interrupt capability.The ADP5587 has keypad lock capability with an option to trigger or not trigger an interrupt at key presses and releases. All communication to the main processor is done using one interrupt line and two I2C-compatible interface lines. The ADP5587 can be configured as a keypad matrix of up to 8 rows ? 10 columns (a maximum of 80 keys).When the ADP5587 is used for smaller keypad matrices, unused row and column pins can be reconfigured to act as general-purpose inputs or outputs. R0 to R7 denote the row pins of the matrix, whereas C0 to C9 denote the column pins. At power-up, all rows and columns default to GPIs and must be programmed to function as part of the keypad matrix or as GPOs.Two options for I2C addresses exist for the LFCSP package to reduce the chance of port contention and allow up to two?ADP5587 ICs to operate on the same I2C bus (see the Ordering Guide).Applications Keypad and I/O expander designed for QWERTY type phones that require a large keypad matrix

The LT3960 is a robust high speed transceiver that extends a single-master I2C bus through harsh or noisy environments at up to 400kbps using the CAN-physical layer. One LT3960 sits near the I2C master, creating from SCL and SDA equivalent differential buses (I2CAN) on two twisted pairs. At the other end of the twisted pairs, a second LT3960 recreates the I2C bus locally for any slave I2C devices. A built-in 3.3V LDO powers both the I2C and I2CAN buses from a single input supply from 4V to 60V. Alternatively, the LT3960 can be powered directly from a 3.3V or 5V supply.The LT3960 is available in a 10-lead MSOP package.APPLICATIONSIndustrial NetworkingAutomotive NetworkingRemote Sensors
