DC component of input voltage is ignored due to C1
Figure 8. Telephone Ring Detector/A.C. Line CMOS Input Isolator
The H11AG1M uses less input power than the neon bulb traditionally used to monitor telephone and line voltages.
Additionally. response time can be tailored to ignore telephone dial tap, switching transients and other undesired
signals by modifying the value of C2. The high impedance to line voltage also can simply board layout spacing
requirements.
