Microsemi Corp. Telecom LE75183AFSC

The LE75183AFSC is a monolithic solid-state Line Card Access Switch (LCAS) designed for analog line card applications. It features a compact surface-mount package and operates at a supply voltage of 5 V with low power consumption. The device provides clean, bounce-free switching and is equipped with built-in current limiting, thermal shutdown, and protection for Subscriber Line Interface Circuits (SLIC). It supports make-before-break and break-before-make operation, ensuring reliable switching without impulse noise. The LE75183AFSC is compatible with TTL logic control and requires only one external protector, simplifying circuit design. It is suitable for use in central offices, digital loop carriers (DLC), private branch exchanges (PBX), and hybrid fiber-coaxial (HFC) applications.
