Description

The HC3-5502B-5 is an electronic component model in the IC Chips category. It is a single IC chip that incorporates various BORSHT functions, including DC battery feed, ring relay driver, supervisory, and hybrid functions. The Intersil SLIC is designed to maintain transmission performance even in the presence of externally induced longitudinal currents. With its unique dielectric isolation process, it can operate directly with a wide range of station battery voltages.
