intersil HC-5524 handbook

The HC-5524 is a 24V PABX SLIC with 25mA loop feed. It is manufactured using a Dielectric Isolation (DI) process and is designed to serve 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 provides various BORSCHT functions including battery feed with subscriber loop current limiting, overvoltage protection, ring relay driver, supervisory signaling functions, hybrid functions (with external Op-Amp), and test (or battery reversal) relay driver. Additionally, it offers selective denial of power to subscriber loops, programmable subscriber loop current limit, thermal shutdown with alarm output, and line fault protection. The HC-5524 SLIC is suitable for line card designs in PBX and DLC systems, serving as a replacement for traditional transformer solutions.
