2-Channel, Bidirectional I2C Bus Buffer ICs Maximize Speed and Noise Margin in Networking, Server, and ATCA Designs
Intersil’s ISL3300x Series Prevents Signal Degradation and Data Transmission Errors, Provides Hot-Swap Capabilities; Available in Industry’s Most Compact Packaging
MILPITAS, CA, Apr. 22, 2010–Intersil Corporation (NASDAQ Global Select: ISIL), a world leader in the design and manufacture of high-performance analog and mixed signal semiconductors, today released a new series of 2-wire bidirectional I2C buffers that enable error-free data transmission in heavily-loaded I2C bus configurations.
The ISL3300x series, which includes the ISL33001, ISL33002, and ISL33003, are ideal for use in servers, networking and telecommunications infrastructure equipment, and other applications that need hot swap board insertion and bus isolation. The buffer minimizes bus idle time and propagation delay, increasing maximum overall system speed. Hot swap capability prevents corruption of data and clock lines when I2C devices are plugged into live backplanes, so users can exchange boards on a live bus with no data disruption.
All three versions are capable of 400 kHz operation (I2C fast-mode data rate) and operate on 2.3V to 5.5V supplies. All of the ISL3300x buffers also include rise-time accelerator circuitry to improve signal integrity and reduce power consumption from passive bus pull-up resistors.
Each device also includes features designers can apply in specific applications. For example, the ISL33002 and ISL33003 incorporate a logic level translator, so devices can be interfaced at mixed logic voltage levels. The ISL33001 and ISL33003 include an enable pin for low current shutdown, while the ISL33002 provides an accelerator disable pin.
Pricing and Availability
The ISL3300x series is available now in compact, space saving 8-lead 3x3 TDFN and 8-lead MSOP packages, with prices starting at $1.39 each in 1,000-piece units.
