The LTM2884 is a complete galvanically isolated USB 2.0 compatible ?Module? (micromodule) transceiver. An upstream supply powers both sides of the interface through an integrated, isolated DC/DC converter.The LTM2884 is ideal for isolation in host, hub, bus splitter or peripheral device applications. It is compatible with USB 2.0 full speed (12Mbps) and low speed (1.5Mbps) operation. Automatic speed selection configures integrated pull-up resistors on the upstream port to match those sensed on the downstream device.The isolator ?Module technology uses coupled inductors and an isolated power transformer to provide isolation between the upstream and downstream USB interface. This device is ideal for systems requiring isolated ground returns or large common mode voltage variations. Uninterrupted communication is guaranteed for common mode transients greater than 30kV/?s.Enhanced ESD protection allows this part to withstand up to ?15kV (human body model) on the USB transceiver interface pins to local supplies and ?15kV through the isolation barrier to supplies without latch-up or damage.Applications Isolated USB Interfaces Host, Hub, or Device Isolation Industrial/Medical Data Acquisition

The LTM2889 is a complete galvanically-isolated Controller Area Network (CAN) ?Module? (micromodule) transceiver. No external components are required ? a single supply powers both sides of the interface through an integrated, isolated DC/DC converter. Separate versions are available for 3.3V and 5V power supplies. The dual voltage CAN transceiver and the adjustable regulator allow 3.3V or 5V isolated power with either the 3.3V or 5V version.Coupled inductors and an isolation power transformer provide 2500VRMS 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 ranges. Communication remains uninterrupted for common mode transients greater than 30kV/?s.Supports up to 4Mbps CAN with Flexible Data Rate (CAN FD). 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 ?25kV Human Body Model (HBM) on the transceiver interface pins and ?10kV HBM across the isolation barrier without latchup or damage.Applications Isolated CAN Bus Interface Industrial Networks DeviceNet Applications

The LTC1543 is a 3-driver/3-receiver multiprotocol transceiver that operates from a single 5V supply.

Cable termination may be implemented using the LTC1344A software-selectable cable termination chip or by using existing discrete designs.The LTC1543 runs from a single 5V supply using an internal charge pump that requires only five space-saving surface mounted capacitors. The part is available in a 28-lead SSOP surface mount package.Applications Data Networking CSU and DSU Data Routers

The LTC4316 enables the hardwired address of one or more I2C or SMBus slave devices to be translated to a different address. This allows slaves with the same hardwired address to coexist on the same bus. Only discrete resistors are needed to select the new address and no software programming is required. Up to 127 different address translations are available.The LTC4316 incorporates a pass-through mode which disables the address translation and allows general call addressing by the master. The LTC4316 is designed to automatically recover from abnormal bus conditions like bus stuck low or premature STOP bits.

The AD2425W is fully configurable supporting both master and slave functionality.The AD2425W is targeted for use in wiring intensive applications where reducing the weight or complexity of existing cable harnesses is a primary system design objective. These applications include Premium Audio Systems, Active Noise Cancellation, and In-Car Communications.Applications Automotive audio communication link Active noise cancellation Microphone arrays for hands free and in car communication

The LTC4310 provides bidirectional I2C communications between two I2C buses whose grounds are isolated from one another. Each LTC4310 encodes I2C bus logic states into signals that are transmitted across an isolation barrier to another LTC4310. The receiving LTC4310 decodes the transmission and drives its l2C bus to the appropriate logic state. The isolation barrier can be bridged by an inexpensive Ethernet, or other transformer, to achieve communications across voltage differences reaching thousands of volts, or it can be bridged by capacitors for lower voltage isolation. The LTC4310-1 is intended for use in 100kHz I2C systems. The LTC4310-2 is intended for 400kHz I2C systems.Rise time accelerators provide strong pull-up currents on SCL and SDA rising edges to meet rise time specifications for heavily loaded systems. Data and clock Hot Swap? circuitry prevent data corruption when a card is inserted into or removed from a live bus. When a bus is stuck low for 37ms, the LTC4310 turns off its pull-down devices and generates up to sixteen clocks and a STOP bit in an attempt to free the bus. Driving EN low sets the LTC4310 in a very low current shutdown mode to conserve power.Applications Isolated I2C, SMBus and PMBus Interfaces Isolated Power Supplies Positive-to-Negative Rail Communications Power-over-Ethernet
