15 degrees. If the contention persists, the thermal
shutdown/reenable cycle repeats until the fault is cleared.
Receivers stay operational during thermal shutdown.
Low Power Shutdown Mode
This BiCMOS transceiver uses a fraction of the power
required by their bipolar counterparts, but it also includes a
shutdown feature that reduces the already low quiescent I
to a 50nA trickle. It enters shutdown whenever the receiver

and driver are simultaneously disabled (RE = V
DE = GND) for a period of at least 600ns. 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 8, 9,
10, 11 and 12, at the end of the Electrical Specification table
on page 6, for more information.
