The ADuM520x are dual channel digital isolators with isoPower, an integrated, isolated dc-to-dc converter. Based onthe Analog Devices, Inc., iCoupler® technology, the dc-to-dcconverter provides up to 500 mW of regulated, isolated powerwith 5.0 V input and 5.0 V output voltage, or 200 mW of power with 3.3 V input and 3.3 V output voltage. This eliminates the need for a separate isolated dc-to-dc converter in low power isolated designs. The Analog Devices chip scale transformer iCoupler technology is used for the isolation of the logic signals as well as for the dc-to-dc converter. The result is a small form factor, total isolation solution.ADuM520x units may be used in combination with ADuM5401, ADuM5402, ADuM5403, ADuM5404 and ADuM5000 with isoPower® to achieve higher output power levels and greater channel counts (see the Increasing Available Power section).The ADuM520x isolators provide two independent isolationchannels in a variety of channel configurations and data rates(see the Ordering Guide for options).isoPower uses high frequency switching elements to transfer power through its transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissionsstandards.

The LTC2856-1, LTC2856-2, LTC2857-1, LTC2857-2, LTC2858-1 and LTC2858-2 are low power, RS485/RS422 transceivers operating on 5V supplies at maximum data rates of 20Mbps or 250kbps for low EMI. The receiver has a one-eighth unit load, supporting up to 256 nodes per bus (C, I-Grade), and a fail-safe feature that guarantees a high output state under conditions of floating or shorted inputs.The driver maintains a high output impedance over the entire common mode range when disabled or when the supply is removed. Excessive power dissipation caused by bus contention or a fault is prevented by current limiting all outputs and by thermal shutdown.Enhanced ESD protection allows these parts to withstand ±15kV (human body model) on the transceiver interface pins without latch-up or damage.

The MAX7319 2-wire serial-interfaced peripheral features eight input ports with selectable internal pullups, overvoltage protection to +6V, and transition detection with interrupt output.All input ports are continuously monitored for state changes (transition detection). Transitions are latched, allowing detection of transient changes. Any combination of inputs can be selected using the interrupt mask to assert the active-low INT output. When the MAX7319 is subsequently accessed through the serial interface, any pending interrupt is cleared.The +5.5V tolerant active-low RST input clears the serial interface, terminating any I²C communication to or from the MAX7319.The MAX7319 uses two address inputs with four-level logic to allow 16 I²C slave addresses. The slave address also enables or disables internal 40kΩ pullups in groups of four ports.The MAX7319 supports hot insertion. All eight input ports, the serial interface SDA, SCL, AD0, AD2, active-low INT, and active-low RST remain high impedance in power-down (V+ = 0) with up to +6V asserted on them.The MAX7319 is one device in a family of pin-compatible port expanders with a choice of input ports, open-drain I/O ports, and push-pull output ports.The MAX7319 is available in 16-pin QSOP and 16-pin TQFN packages, and is specified over the automotive temperature range (-40°C to +125°C).ApplicationsCell PhonesNotebooksSAN/NASSatellite RadioServers
