ISL83077E Datasheet Rs-485/rs-422 Transceivers

Manufacturer: Renesas

Overview: DATASHEET ISL83070E/71E/72E/73E/75E/76E/77E/78E ±15kV ESD Protected, 3.3V, Full Fail-safe, Low Power, High Speed or Slew Rate Limited, RS-485/RS-422 Transceivers The ISL8307xE (ISL83070E, ISL83071E, ISL83072E, ISL83073E, ISL83075E, ISL83076E, ISL83077E, ISL83078E) are BiCMOS 3.3V powered, single transceivers that meet both the RS-485 and RS-422 standards for balanced communication. These devices have very low bus currents (+125µA/-100µA), 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 use 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.
