RS-485 and RS-422 standards for balanced communication. Each device has low bus currents (+220uA/-150uA), so it presents a “1/5 unit load” to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specifications 32 unit load maximum, and without using repeaters. Receiver (Rx) inputs feature a “full fail-safe” design, which ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. The ISL3179E half duplex version multiplexes the Rx inputs and Tx outputs to allow a transceiver with an output disable function in 8 Ld packages.
Key Features
High ESD protection on RS-485 I/O pins
ISL3179E : 16.5kV IEC61000
Class 3 HBM level on all other pins (ISL3179E) >9kV
Specified for +125C operation
High data rates up to 40Mbps
5V tolerant logic inputs
1/5 unit load allows up to 160 devices on the bus
Full fail-safe (open, shorted, terminated/undriven) receiver
Hot plug – Tx and Rx outputs remain three-state during power-up
