The LTM2887 is a complete galvanic digital ?Module? (micromodule) isolator. No external components are required. A single 3.3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Available options are compliant with SPI and I2C (master mode only) specifications.The isolated side includes two 5V nominal power supplies, including programmable current limit, each capable of providing more than 100mA of load current. The supplies may be adjusted from their nominal value using a single external resistor.Coupled inductors and an isolation power transformer provide 2500VRMS of isolation between the input and output logic interface. This device is ideal for systems where the ground loop is broken, allowing for a large common mode voltage range. Communication is uninterrupted for common mode transients greater than 30kV/?s.Applications Isolated SPI or I2C Interfaces Industrial Systems Test and Measurement Equipment Breaking Ground Loops

The LTM2885 is a complete galvanically isolated full-duplex RS485/RS422 ?Module? (micromodule) transceiver. No external components are required. A single supply powers both sides of the interface through an integrated, isolated, low noise, efficient 5V output DC/DC converter.Coupled inductors and an isolation power transformer provide 6500VRMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop is broken allowing for large common mode voltage variation. Uninterrupted communication is guaranteed for common mode transients up to 50kV/?s.Maximum data rates are 20Mbps or 250kbps in slew limited mode. Transmit data, DI, and receive data, RO, are implemented with event driven low jitter processing. The receiver has a one-eighth unit load supporting up to 256 nodes per bus. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the transceiver interface pins to isolated supplies and ?25kV through the isolation barrier to logic supplies without latch-up or damage.APPLICATIONS Isolated RS485/RS422 Interface Industrial Networks Breaking RS485 Ground Loops Isolated PROFIBUS-DP Networks

The LTC2846 is a 3-driver/3-receiver multiprotocol transceiver with on-chip cable termination. When combined with the LTC2844 or LTC2845, this chip set forms a complete software-selectable DTE or DCE interface port that supports the RS232, RS449, EIA530, EIA530-A, V.35, V.36 and X.21 protocols. All necessary cable termination is provided inside the LTC2846. The LTC2846 has a boost regulator that takes in a 3.3V input and switches at 1.2MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height.The 5V output drives an internal charge pump that requires only five space-saving surface mounted capacitors. The LTC2846 is available in a 36-lead SSOP surface mount package.Applications Data Networking CSU and DSU Data Routers

The ADN4654/ADN4655/ADN46561? are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1 Gbps with low jitter. The devices integrate Analog Devices, Inc., iCoupler? technology, enhanced for high speed operation to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows drop-in isolation of an LVDS signal chain.The ADN4654/ADN4655/ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated but not driven.For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply. An integrated on-chip low dropout (LDO) regulator can provide the required 2.5 V from an external 3.3 V power supply. The devices are fully specified over a wide industrial temperature range and come in a 20-lead, wide body SOIC_W package with 5 kV rms isolation or in a 20-lead SSOP package with 3.75 kV rms isolation.Applications Isolated video and imaging data Analog front-end isolation Data plane isolation Isolated high speed clock and data links1 Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329.

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
