2-Channel, Bidirectional I-Squared C Bus Buffer ICs Maximize Speed and Noise Margin in Networking, Server, and ATCA

MILPITAS, CA, Apr 22 (MARKET WIRE) --
Intersil Corporation (NASDAQ: 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 I-Squared C buffers
that enable error-free data transmission in heavily-loaded I-Squared C
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 I-Squared C
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 (I-Squared C
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.
