3. Applications
3.1 Line-In-Use (LIU) and Line Polarity Detector
This circuit performs two phone line interface
functions, LIU and line polarity detection. The LIU
output is logic high if the tip to ring voltage is less than
approximately 17V. This will occur whenever a parallel
device on the line such as a telephone or FAX is taken
off hook. This circuit can also be used to detect for the
presence or loss of battery.
The Polarity output indicates the polarity of the phone
line. Whenever tip is positive with respect to ring,
Polarity out will be a logic high.
