The INVALID output always indicates whether or not a
valid RS-232 signal is present at any of the receiver
inputs (see Table 2), giving the user an easy way to
determine when the interface block should power
down. In the case of a disconnected interface cable
where all the receiver inputs are floating (but pulled to
GND by the internal receiver pull down resistors), the
INVALID logic detects the invalid levels and drives the
output low. The power management logic then uses
this indicator to power down the interface block.
Reconnecting the cable restores valid levels at the
receiver inputs, INVALID switches high, and the power
management logic wakes up the interface block.
INVALID can also be used to indicate the DTR or RING
INDICATOR signal, as long as the other receiver inputs
are floating, or driven to GND (as in the case of a
powered down driver). Connecting FORCEOFF and
FORCEON together disables the automatic power-down
feature, enabling them to function as a manual
SHUTDOWN input (see Figure 4).
