These devices have very low bus currents (+125mA/-100mA), so they present a true “1/8 unit load” to the RS-485 bus. This allows up to 256 transceivers on the network without violating the RS-485 specification’s 32 unit load maximum, and without using repeaters. For example, in a remote utility meter reading system, individual meter readings are routed to a concentrator via an RS-485 network, so the high allowed node count minimizes the number of repeaters required. 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. Hot Plug circuitry ensures that the Tx and Rx outputs remain in a high impedance state while the power supply stabilizes. The ISL83070E through ISL83075E utilize slew rate limited drivers which reduce EMI, and minimize reflections from improperly terminated transmission lines, or unterminated stubs in multidrop and multipoint applications. Slew rate limited versions also include receiver input filtering to enhance noise immunity in the presence of slow input signals. The ISL83070E, ISL83071E, ISL83073E, ISL83076E, ISL83077E are configured for full duplex (separate Rx input and Tx output pins) applications. The half duplex versions multiplex the Rx inputs and Tx outputs to allow transceivers with output disable functions in 8 lead packages.

Supply current specification is valid for loaded drivers when DE = 0V. 6. Applies to peak current. See “Typical Performance Curves” for more information. 7. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN. 8. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from entering SHDN. 9. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See “Low Power Shutdown Mode” on page 11. 10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN. 11. Set the RE signal high time >600ns to ensure that the device enters SHDN. 12. Does not apply to the ISL83071E and ISL83077E. 13. ΔtSKEW is the magnitude of the difference in propagation delays of the specified terminals of two units tested with identical test conditions (VCC, temperature, etc.). Only applies to the ISL83076E - 78E. 14. ISL83070E - ISL83075E only. 15. VCC ≥ 3.15V 16. Limits established by characterization and are not production tested. 17. If the Tx or Rx enable function isn’t needed, connect the enable pin to the appropriate supply (see “Pin Descriptions” table) through a 1kΩ to 3kΩ resistor. 18. Parts are 100% tested at +25°C. Full temperature limits are guaranteed by bench and tester characterization.
