±15kV ESD Protected, 5V, Full Fail-Safe,

Fractional (1/8) Unit Load, RS-485/RS-422

Transceivers

The ISL8308XE are BiCMOS, ESD protected, 5V powered,

single transceivers that meet both the RS-485 and RS-422

standards for balanced communication. Each driver output,

and receiver input, is protected against

without latch-up, and unlike competitive products, this Intersil

family is specified for 10% tolerance supplies (4.5V to 5.5V).

These devices have very low bus currents (+125µA/-75µA),

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. Data for all

meters is then read out from the concentrator via a single

access port, or a wireless link.

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.

The ISL83080E, ISL83082E, ISL83083E, ISL83085E 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.

Hot Plug circuitry ensures that the Tx and Rx outputs remain

in a high impedance state until the power supply has

stabilized, and the Tx outputs are fully short circuit protected.

The ISL83080E, ISL83083E, ISL83086E 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.
