World's Fastest RS-485/RS-422 Transceiver Gives Best-in-Class ESD Protection
— The ISL3259E 100Mbps Data Transfer Rate Doubles the Currently Available Data Rates While providing IEC61000 ESD Protection in a Space Saving 3mm x 3mm Package
MILPITAS, CA, Dec 17, 2007 – Intersil Corporation (NASDAQ Global Select: ISIL),
a world leader in the design and manufacture of high-performance analog
semiconductors, today introduced the
ISL3259E
RS-485/RS-422 transceiver, a next-generation interface IC that combines the
industry’s fastest data transmission rate (100Mbps) with an incredibly low 2.6mA
supply current and rugged 15kV IEC61000-4-2 ESD (electro-static discharge)
protection.
In achieving a data rate more than double that of competing devices, the
ISL3259E
allows manufacturers to design the most dependable high data rate systems ever
created, giving unprecedented precision control in factory automation
applications or doubling the throughput in applications requiring large data
transfers.
The majority of higher-end RS-485/RS-422 transceivers are limited to data rates
up to 40Mbps. Precision control of motor positioning in factory automation
systems requires high speed data transfers. With its 100Mbps data rate, clearly
the
ISL3259E leads the way.
In addition, the
ISL3259E
integrates ESD protection that is between 33% and 100% greater than the ESD
ratings of other very high speed transceivers in the marketplace. This allows
for the elimination of external protection components and saves on total costs.
This device’s stellar ESD level is rated at 15kV air gap and 8kV contact
discharge to IEC61000-4-2 on the RS-485/RS-422 bus pins and 9kV HBM on all of
the other pins.
The
ISL3259E has enhanced output differential voltage drive (Vod). The
transceiver Vod is specified to be 40% greater then the voltage specified by the
RS-485 protocol. This enhancement and rugged features make the
ISL3259E
an ideal fit for factory automation applications. Other applications also profit
from the increased noise immunity and enhanced data integrity provided by the
extra large Vod. Parallel networks, like SCSI “fast 40” systems, benefit from
the 100Mbps data rate and the low transceiver and receiver skews, as well as the
4nS part-to-part skews. In addition, the receiver outputs deliver superior low
state currents (typically >30mA at Vol = 1V) to ease the design of
optically-coupled, isolated networks.
To round out the robust performance elements of the
ISL3259E,
the device also has a full fail-safe receiver, current limiting and thermal
shutdown for driver overload protection, and hot plug transmitter and receiver
outputs. These features protect the
ISL3259E
outputs and prevent data corruption when cable faults occur or when a new node
is added to an active bus. This means systems will have enhanced data integrity
and will be more rugged when using the
ISL3259E.
In addition to these enhanced performance benefits, the
ISL3259E
is packaged in a small 3mm x 3mm DFN package for space-savings along with an 8
lead MSOP package option. The tiny package has a 70% smaller PCB footprint than
standard 8-lead SOIC offerings and an integrated thermal slug provides
approximately a 40% improvement in thermal resistance compared to the SOIC
package.
Pricing and Availability
The
ISL3259E is available in DFN and MSOP packaging in 1,000 unit quantities for
$1.33 each.
