HC55171 Data Sheet July 1998 File Number 4323.4 5 REN Ringing SLIC for ISDN Modem/TA and WLL 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 ampliļ¬er 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.
