HC5517B
Low Cost 3 REN Ringing SLIC for ISDN
Modem/TA and WL
The HC5517B low cost, 3 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 HC5517. 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 HC5517B are complex impedance matching,
pulse metering, and transhybrid balance. The HC5517B 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.
