HC55171 General Description

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.
