Renesas Electronics ISL3179EFBZ Dual-Channel Line Transceiver

The Renesas RS-485/RS-422 Transceiver is high ESD protected, 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Device has low bus currents (+220μA/-150μA), so they present a 1/5 unit load to the RS-485 bus. This allows up to 160 transceivers on the network without violating the RS-485 specification’s 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.

High data rates up to 40Mbps
5V tolerant logic inputs
1/5 unit load allows up to 160 devices on the bus
-7V to +12V common-mode input voltage range
Three-state Rx and Tx outputs
Current limiting and thermal shutdown for driver overload protection
Pb-free (RoHS compliant)
