DATASHEET ISL83080E/82E/83E/84E/85E/86E/88E FN6085 Rev 10.00 15kV ESD, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers February 15, 2016 The ISL8308xE are BiCMOS, ESD protected, 5V powered, Features single transceivers that meet both the RS-485 and RS-422 Pb-Free Available (RoHS Compliant) standards for balanced communication. Each driver output, and receiver input, is protected against 15kV ESD strikes RS-485 I/O Pin ESD Protection 15kV HBM without latch-up, and unlike competitive products, this Intersil Class 3 ESD Protection (HBM) on all Pins >7kV family is specified for 10% tolerance supplies (4.5V to 5.5V). Tiny MSOP Packages Save 50% Board Space These devices have very low bus currents (+125A/-75A), Full Fail-Safe (Open, Short, Terminated and Floating) so they present a true 1/8 unit load to the RS-485 bus. This Receivers allows up to 256 transceivers on the network without violating Hot Plug Circuitry (ISL83080E, ISL83082E, ISL83083E, the RS-485 specifications 32 unit load maximum, and without ISL83085E) using repeaters. For example, in a remote utility meter reading - Tx and Rx Outputs Remain Three-state During system, individual meter readings are routed to a concentrator Power-up/Power-down via an RS-485 network, so the high allowed node count minimizes the number of repeaters required. Data for all True 1/8 Unit Load Allows up to 256 Devices on the Bus meters is then read out from the concentrator via a single Specified for Single 5V, 10% Tolerance, Supplies access port, or a wireless link. High Data Rates . up to 10Mbps Receiver (Rx) inputs feature a Full Fail-Safe design, which Low Quiescent Supply Current . 530A ensures a logic high Rx output if Rx inputs are floating, Ultra Low Shutdown Supply Current 70nA shorted, or terminated but undriven. -7V to +12V Common Mode Input Voltage Range The ISL83080E, ISL83082E, ISL83083E, ISL83084E, ISL83085E utilize slew rate limited drivers which reduce EMI, Half and Full Duplex Pinouts and minimize reflections from improperly terminated Three-State Rx and Tx Outputs (Except ISL83084E) transmission lines, or unterminated stubs in multidrop and Current Limiting and Thermal Shutdown for driver multipoint applications. Slew rate limited versions also include Overload Protection receiver input filtering to enhance noise immunity in the presence of slow input signals. Applications Hot Plug circuitry ensures that the Tx and Rx outputs remain Automated Utility Meter Reading Systems in a high impedance state until the power supply has stabilized, and the Tx outputs are fully short circuit protected. High Node Count Systems Factory Automation The ISL83080E, ISL83083E, ISL83084E, ISL83086E are configured for full duplex (separate Rx input and Tx output Field Bus Networks pins) applications. The half duplex versions multiplex the Rx Security Camera Networks inputs and Tx outputs to allow transceivers with output disable functions in 8 Ld packages.
