Intersil HC-5524
The HC-5524 telephone Subscriber Line Interface Circuit integrates most of the BORSCHT functions on a monolithic IC. The device is manufactured in a Dielectric Isolation (DI) process and is designed for use as a 24V interface between the traditional telephone subscriber pair (Tip and Ring) and the low voltage filtering and coding/decoding functions of the line card. The SLIC also maintains specified transmission performance in the presence of externally induced longitudinal currents.| Part No. | HC-5524 |
