ISL3178AE
±15kV ESD Protected, 3.3V, Full Fail-Safe,
Low Power, High Speed or Slew Rate
Limited, RS-485/RS-422 Transceivers
The Intersil ISL3178AE is ±15kV IEC61000 ESD protected,
3.3V-powered, single transceivers that meet both the
RS-485 and RS-422 standards for balanced communication.
This device has very low bus currents (+125mA/-100mA),
which presents 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 ISL3178AE is a half duplex version. It multiplexes the
Rx inputs and Tx outputs to allow transceivers with output
disable functions in an 8 Ld package.
