ISL3179E, ISL3180E
High ESD Protected, 40Mbps, 3.3V, Full Fail-Safe RS-485/RS-422 Transceivers
The ISL3179E and ISL3180E are high ESD protected (see Table 2 on page 2), 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. Each 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.
The ISL3180E is configured for full duplex applications.
