ISL81485
ISL81485 is RS-485/RS-422 Transceiver manufactured by Renesas.
features a larger output voltage and higher data rate to benefit high speed applications.
Unlike petitive devices, this Intersil transceiver is specified for 10% tolerance supplies (4.5V to 5.5V), and it delivers a much larger worst case differential output voltage (2.0V pared to the typical 1.5V) over the full supply range. The increased output voltage translates into longer reach, or better data integrity, at the 30Mbps data rate.
This device presents a “1 unit load” to the RS-485 bus, which allows up to 32 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...
