The ISO1540 and ISO1541 devices are low-power, bidirectional isolators that are compatible with I 2C interfaces. These devices have logic input and output buffers that are separated by Texas Instruments Capacitive Isolation technology using a silicon dioxide (SiO2 ) barrier. When used with isolated power supplies, these devices block high voltages, isolate grounds, and prevent noise currents from entering the local ground and interfering with or damaging sensitive circuitry.
This isolation technology provides for function, performance, size, and power consumption advantages when compared to optocouplers. The ISO1540 and ISO1541 devices enable a complete isolated I 2C interface to be implemented within a small form factor. The ISO1540 has two isolated bidirectional channels for clock and data lines while the ISO1541 has a bidirectional data and a unidirectional clock channel. The ISO1541 is useful in applications that have a single master while the ISO1540 is suitable for multimaster applications. For applications where clock stretching by the slave is possible, the ISO1540 device should be used.

Analog Devices / Linear Technology LT3465AES6#TRMPBF0 out of 5(0)
The LT3465AES6#TRMPBF is a step-up DC/DC Converter designed to drive up to six LEDs in series from a Li-ion cell. Series connection of the LEDs provides identical LED currents and eliminates the need for ballast resistors. This device integrates the Schottky diode required externally on competing devices. Additional features include output voltage limiting when LEDs are disconnected, one-pin shutdown and dimming control. The LT3465 switches at 1.2MHz, allowing the use of tiny external components. The faster LT3465A switches at 2.4MHz. Constant frequency switching results in low input noise and a small output capacitor. Just 0.22µF is required for 3, 4 or 5-LED applications.
- Internal soft-start
- Inherently matched LED current
- No external Schottky diode required
- Open LED protection
- Requires only 0.22µF output capacitor

Marvell 88E1121RA0-TFE1C0000 out of 5(0)
The Alaska® Ultra 88E1111 Gigabit Ethernet Transceiver is a physical layer device for Ethernet 1000BASE-T, 100BASE-TX, and 10BASE-T applications. It is manufactured using standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair. The 88E1111 device incorporates the Marvell Virtual Cable Tester® (VCT™) feature, which uses Time Domain Reflectometry (TDR) technology for the remote identification of potential cable malfunctions, thus reducing equipment returns and service calls. Using VCT, the Alaska 88E1111 device detects and reports potential cabling issues such as pair swaps, pair polarity and excessive pair skew. The device will also detect cable opens, shorts or any impedance mismatch in the cable and report accurately within one meter the distance to the fault.
The 88E1111 device supports the Gigabit Media Independent Interface (GMII), Reduced GMII (RGMII), Serial Gigabit Media Independent Interface (SGMII), the Ten-Bit Interface (TBI), and Reduced TBI (RTBI) for direct connection to a MAC/Switch port. The 88E1111 device incorporates an optional 1.25 GHz SERDES (Serializer/Deserializer). The serial interface may be connected directly to a fiber-optic transceiver for 1000BASE-T/1000BASE-X media conversion applications. Additionally, the 88E1111 device may be used to implement 1000BASE-T Gigabit Interface Converter (GBIC) or Small Form Factor Pluggable (SFP) modules.
The 88E1111 device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate. The device achieves robust performance in noisy environments with very low power dissipation.
The 88E1111 device is offered in three different package options including a 117-Pin TFBGA, a 96-pin BCC featuring a body size of only 9 x 9 mm, and a 128 PQFP package.SKU: W007840
