Disabling both the driver and the receiver for less than 60ns
guarantees that the transceiver will not enter shutdown.
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
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.
CC
the receiver and driver are simultaneously disabled
(RE = V
and DE = GND) for a period of at least 600ns.
