Description
Support is limited to customers who have already adopted these products.
The Intersil ISL4486 and ISL81486 are BiCMOS, 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication, and feature the larger output voltage and higher data rate - up to 40Mbps - required by high speed PROFIBUS applications. Unlike competitive products, these Intersil devices are specified for 10% tolerance supplies (4. 5V to 5. 5V) and deliver at least a 2. 3V differential output voltage over this supply range. At the 5% tolerance specified by many competitors, the ISL4486 delivers an unsurpassed 2. 5V differential signal into a 54Ω total load. This translates into longer reach, or better data integrity, at the exceptional 40Mbps data rate. SCSI applications benefit from the ISL4486's low receiver and transmitter part-to-part skews, which make it perfect for high speed parallel applications where large numbers of bits must be simultaneously captured. The low bit-to-bit skew eases the timing constraints on the data latching signal. These devices present a 0. 6 unit load to the RS-485 bus, which allows up to 50 transceivers on the network. Receiver (Rx) inputs feature a fail-safe if open design, which ensures a logic high Rx output if Rx inputs are floating. Driver (Tx) outputs are short circuit protected, even for voltages exceeding the power supply voltage. Additionally, on-chip thermal shutdown circuitry disables the Tx outputs to prevent damage if power dissipation becomes excessive.
