HC55171B
Low Cost 5 REN Ringing SLIC
for ISDN Modem/TA and WL
The HC55171B low cost, 5 REN ringing SLIC is designed to
accommodate a wide variety of short loop applications and
provides the same degree of flexibility as the high
performance HC55171. The flexible features include open
circuit tip to ring DC voltages, user defined ringing
waveforms, ring trip detection thresholds, and loop current
limits that can be tailored for many applications. Additional
features of the HC55171B are complex impedance
matching, pulse metering, and transhybrid balance. The
HC55171B is designed for use in short loop, low cost
systems where traditional ring generation is not
economically feasible.
The device is manufactured in a high voltage Dielectric
Isolation (DI) process. The DI process provides substrate
latch up immunity, resulting in a robust system design. A
thermal shutdown with an alarm output and line fault
protection are also included for operation in harsh
environments.
