Low Power Shutdown Mode (ISL83483, ISL83485,
ISL83491 Only)
These CMOS transceivers all use a fraction of the power
required by their bipolar counterparts, but the ISL83483,
ISL83485, ISL83491 include a shutdown feature that
reduces the already low quiescent ICC to a 15nA trickle.
They enter shutdown whenever the receiver and driver are
simultaneously disabled (RE =VCC and DE = GND) for a
period of at least 300ns. Disabling both the driver and the
receiver for less than 80ns guarantees that shutdown is not
entered.
Note that receiver and driver enable times increase when
these devices enable from shutdown. Refer to Notes 5-9, at
the end of the Electrical Specification table, for more
information.
Typical Performance Curves VCC = 3.3V, TA = 25oC, ISL83483 thru ISL83491; Unless Otherwise Specified
