ISL8490IBZ-T 1/1 Transceiver Full RS422 RS485 8-SOIC 70 MV 5MbpsThe ISL8485, ISL8490, and ISL8491 RS-485/RS-422 devices are BiCMOS
5V powered, single transceivers that meet both the RS-485 and
RS-422 standards for balanced communication. Unlike competitive
devices, this family is specified for 10% tolerance supplies (4.5V
to 5.5V). The ISL8485, ISL8490, and ISL8491 feature data rates up
to 5Mbps. All devices present a single unit load to the RS-485 bus,
which allows up to 32 transceivers on the network. The receiver
(Rx) inputs feature a “fail-safe if open” design, which ensures a
logic high Rx output if the Rx inputs are floating. The 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. The ISL8490 and ISL8491 are
configured for full duplex (separate Rx input and Tx output pins)
applications. Half duplex configurations (ISL8485) multiplex the Rx
inputs and Tx outputs to allow transceivers with Rx and Tx disable
functions in 8 Ld packages.
