Intersil HC5509A1R3060 Subscriber Line Interface Circuit Datasheet
The Intersil HC5509A1R3060 is a Subscriber Line Interface Circuit (SLIC) manufactured using a Dielectric Isolation (DI) process. It integrates most BORSCHT functions on a monolithic IC to serve as a high-voltage interface between the telephone subscriber pair and low-voltage filtering or coding/decoding functions in line cards.
Key features include controlled supply of battery feed current with programmable limits, internal ring relay and utility relay drivers, and high impedance mode for the subscriber loop. The device supports selective power denial to subscribers while maintaining voice path activity and includes an on-chip operational amplifier for 2-wire impedance matching.
