UC5603J TI Telecom IC | SLIC | 100V, 50mA, 5 REN

Product Overview

The UC5603J is a high-performance Subscriber Line Interface Circuit (SLIC) from Texas Instruments, designed for telecom and datacom applications. It integrates a battery feed, overvoltage protection, and ring relay driver in a single 24-pin PDIP package. The device operates from a single +5V supply and provides a programmable current limit up to 50mA, supporting loop lengths up to 5 REN (Ringer Equivalence Number). With a maximum voltage rating of 100V, it is suitable for both on-hook and off-hook signaling in POTS (Plain Old Telephone Service) systems.
