Microchip Technology, Inc. Telecom LE75183BFSCT

The LE75183BFSCT is a monolithic solid-state switch designed for use in telecom applications, specifically as a Line Card Access Switch (LCAS) within the VoiceEdge,Ñ¢ family VE750 series. It provides power ringing access and test access on analog line cards, serving as a solid-state alternative to traditional electromechanical relays. The device features low impulse noise, clean and bounce-free switching, and low matched ON-resistance, which enhances its reliability and performance. This switch operates at a supply voltage of 5 V and is characterized by very low power consumption. It includes built-in current limiting, thermal shutdown, and protection for Subscriber Line Interface Circuits (SLIC). The device is compatible with TTL logic control and requires only one external protector, simplifying the design process. The LE75183BFSCT is available in a compact surface-mount package, making it suitable for space-constrained applications. It is also pin-for-pin compatible with Zarlink,Äôs L7583A/B/C devices, facilitating integration into existing designs.
