• Manufacturer Part Number: ISL83088E
• Description: (ISL83080E - ISL83088E) RS-485/RS-422 Transceivers
• Manufacturer: Intersil Corporation

Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power
required by their bipolar counterparts, but they also include a
shutdown feature that reduces the already low quiescent I
to a 70nA trickle. These devices enter shutdown whenever
the receiver and driver are simultaneously disabled

Disabling both the driver and the receiver for less than 60ns
guarantees that the transceiver will not enter shutdown.
Note that receiver and driver enable times increase when the
transceiver enables from shutdown. Refer to Notes 7-11, at
the end of the Electrical Specification table, for more
information.
