allowing the die to cool. The drivers automatically
re-enable after the die temperature drops about 15°C.
If the contention persists, the thermal
shutdown/re-enable cycle repeats until the fault is
cleared. Receivers stay operational during thermal
shutdown.
Low Power Shutdown Mode
These CMOS transceivers all use a fraction of the power
required by competitive devices, but they also include a
shutdown feature that reduces the already low quiescent
ICC to a 10μA trickle. These devices enter shutdown
whenever the receiver and driver are simultaneously
disabled (RE = VCC and 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
Specification” table on page 9, for more information.
