These devices have very low bus currents (+125A/-100A), so they present a true 1/8 unit load to Full fail-safe (open, short, terminated/floating) receivers the RS-485 bus. This allows up to 256 transceivers on the Hot plug - Tx and Rx outputs remain three-state during network without violating the RS-485 specifications 32 unit power-up (only versions with output enable pins) load maximum, and without using repeaters. For example, in True 1/8 unit load allows up to 256 devices on the bus a remote utility meter reading system, individual meter readings are routed to a concentrator using an RS-485 Single 3.3V supply network, so the high allowed node count minimizes the High data rates . up to 20Mbps number of repeaters required. Low quiescent supply current .800A (Max) Receiver (Rx) inputs feature a Full Fail-Safe design, which - Ultra low shutdown supply current .10nA ensures a logic high Rx output if Rx inputs are floating, shorted, or terminated but undriven. -7V to +12V common-mode input/output voltage range Hot Plug circuitry ensures that the Tx and Rx outputs remain Half and full duplex pinouts in a high impedance state while the power supply stabilizes. Three state Rx and Tx outputs available The ISL3170E through ISL3175E utilize slew rate limited Current limiting and thermal shutdown for driver overload drivers which reduce EMI, and minimize reflections from protection improperly terminated transmission lines, or unterminated Tiny MSOP packages consume 50% less board space stubs in multidrop and multipoint applications. Slew rate limited versions also include receiver input filtering to Pb-free (RoHS compliant) enhance noise immunity in the presence of slow input signals. Applications The ISL3170E, ISL3171E, ISL3173E, ISL3174E, ISL3176E, and ISL3177E are configured for full duplex (separate Rx Automated utility meter reading systems input and Tx output pins) applications. The half duplex High node count systems versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 Ld packages.
