computer to power up the microprocessor and
the
SP2XXB/SP213
drivers. After the supply
voltage to the
SP2XXB/SP213
reaches +5.0V,
the SHUTDOWN pin can be disabled, taking
the
SP2XXB/SP213
out of the shutdown mode.
All receivers that are active during shutdown
maintain 500mV (typ.) of hysteresis.
A typical application of this function would be
where a modem is interfaced to a computer in a
power–down mode. The ring indicator signal
from the modem could be passed through an
active receiver in the
SP2XXB/SP213
that is
itself in the shutdown mode. The ring indicator
signal would propagate through the
SP2XXB/
SP213
to the power management circuitry of the
