“World's fastest” RS-485/RS-422 transceiver with top ESD protection
( 01 Apr 2008 )
The ISL3259E RS-485/RS-422 transceiver developed by Intersil Corporation is a next-generation interface IC that combines what’s said to be the industry’s fastest data transmission rate (100Mbps) with a very 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 a highly dependable high data rate system, giving precision control in factory automation applications or doubling the throughput in applications requiring large data transfers.
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 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.
