ISL8483EIBZ-T

These Intersil RS-485, RS-422 devices are ESD protected, BiCMOS 5V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each driver output/receiver input is protected against ±15kV ESD strikes, without latch-up. Unlike competitive devices, this Intersil family is specified for 10% tolerance supplies (4.5V to 5.5V) Data rates up to 10Mbps are achievable by using the ISL8485E which features higher slew rates. Receiver (Rx) inputs feature a “fail-safe if open” design, which ensures a logic high Rx output, if Rx inputs are floating. These half duplex configurations multiplex the Rx inputs and Tx outputs to allow transceivers with Rx and Tx disable functions in 8 lead packages.
