DATASHEET ISL83070E/71E/72E/73E/75E/76E/77E/78E FN6115 15kV ESD Protected, 3.3V, Full Fail-safe, Low Power, High Speed or Slew Rate Rev 5.00 October 5, 2012 Limited, RS-485/RS-422 Transceivers The Intersil ISL8307XE are BiCMOS 3.3V powered, single Features transceivers that meet both the RS-485 and RS-422 Pb-Free (RoHS Compliant) standards for balanced communication. These devices have very low bus currents (+125mA/-100mA), so they present a RS-485 I/O Pin ESD Protection 15kV HBM true 1/8 unit load to the RS-485 bus. This allows up to 256 - Class 3 ESD Level on all Other Pins >7kV HBM transceivers on the network without violating the RS-485 Full Fail-safe (Open, Short, Terminated/Floating) specifications 32 unit load maximum, and without using Receivers repeaters. For example, in a remote utility meter reading Hot Plug - Tx and Rx Outputs Remain Three-state During system, individual meter readings are routed to a Power-up (Only Versions with Output Enable Pins) concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required. True 1/8 Unit Load Allows up to 256 Devices on the Bus Receiver (Rx) inputs feature a Full Fail-Safe design, which Single 3.3V Supply ensures a logic high Rx output if Rx inputs are floating, High Data Rates up to 20Mbps shorted, or terminated but undriven. Low Quiescent Supply Current .800A (Max) Hot Plug circuitry ensures that the Tx and Rx outputs remain - Ultra Low Shutdown Supply Current .10nA in a high impedance state while the power supply stabilizes. -7V to +12V Common Mode Input/Output Voltage Range The ISL83070E through ISL83075E utilize slew rate limited Half and Full Duplex Pinouts drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated Three State Rx and Tx Outputs Available stubs in multidrop and multipoint applications. Slew rate limited Current Limiting and Thermal Shutdown for driver versions also include receiver input filtering to enhance noise Overload Protection immunity in the presence of slow input signals. Tiny MSOP package offering saves 50% board space The ISL83070E, ISL83071E, ISL83073E, ISL83076E, ISL83077E are configured for full duplex (separate Rx input Applications and Tx output pins) applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers Automated Utility Meter Reading Systems with output disable functions in 8 lead packages.
