3 REN Ringing SLIC For ISDN Modem/TA
and WLL
he HC5517 is a ringing SLIC designed to accommodate a wide
variety of local loop applications. The various applications
include, basic POTS lines with answering machines and fax
capabilities, ISDN networks, wireless local loop, and hybrid
fiber coax (HFC) terminals. The HC5517 provides a high
degree of flexibility with open circuit tip to ring DC voltages, user
defined ringing waveforms (sinusoidal to square wave), ring trip
detection thresholds and loop current limits that can be tailored
for many applications. Additional features of the HC5517 are
complex impedance matching, pulse metering and transhybrid
balance. The HC5517 is designed for use in systems where a
separate ring generator is not economically feasible.
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. Together with a secondary protection
diode bridge and “feed” resistors, the device will withstand
1000V lightning induced surges, in a plastic package.
A thermal shutdown with an alarm output and line fault
protection are also included for operation in harsh
environments.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
NOTES:
1. θJA is measured with the component mounted on an evaluation PC board in free air.
2. All grounds (AGND, BGND) must be applied before VCC or VBAT. Failure to do so may result in premature failure of the part. If a user wishes
to run separate grounds off a line card, the AG must be applied first.
