The HC55171 is backward compatible to the HC5517 with
the added capability of driving 5 REN loads. The HC55171 is
ideal for any modem or remote networking access
application that requires plain old telephone service POTS,
capability. The linear amplifier design allows a choice of
Sinusoidal, Square wave or Trapezoidal ringing. The voltage
feed architecture eliminates the need for a high current gain
node achieving improved system noise immunity, an
advantage in highly integrated systems.
The device is manufactured in a high voltage Dielectric
Isolation (DI) process with an operating voltage range from
-16V, for off-hook operation and -80V for ring signal injection.
The DI process provides substrate latch up immunity,
resulting in a robust system design.
