DS26303L-120+

DS26303L-120+ Description

The DS26303L-120+ is an advanced 8-channel Line Interface Unit (LIU) designed for high-performance telecom applications. Manufactured by Analog Devices Inc./Maxim Integrated, this IC operates within a 3.135V to 3.465V supply range, drawing a nominal 250mA current. It is housed in a 144-LQFP package and is optimized for surface-mount assembly, making it suitable for compact, high-density PCB designs. Although marked as Obsolete, it remains a robust solution for legacy systems, offering LIU functionality with compliance to ROHS3 and REACH Unaffected standards. Its Moisture Sensitivity Level (MSL 3) ensures reliability in controlled environments.

DS26303L-120+ Features

• 8-channel LIU for scalable telecom interfaces.
• Wide operating temperature range (0°C to 70°C) for stable performance in varied conditions.
• Low-voltage operation (3.3V nominal) with efficient power consumption.
• Surface-mount compatibility (144-LQFP) for space-constrained designs.
• ROHS3 Compliant and EAR99 classified, ensuring global regulatory adherence.
• LIU-specific interface for seamless integration into telecom infrastructure.

DS26303L-120+ Applications

• Legacy telecom systems requiring multi-channel LIU support.
• Digital cross-connect systems (DCS) and PBX equipment.
• T1/E1 line cards and network access modules.
• Central office (CO) and customer premises equipment (CPE) deployments.
• High-density communication routers where space and power efficiency are critical.

Conclusion of DS26303L-120+

The DS26303L-120+ is a reliable, multi-channel LIU solution for telecom applications, combining low-power operation, compact packaging, and regulatory compliance. While obsolete, its 8-channel architecture and 3.3V compatibility make it ideal for maintaining or upgrading legacy systems. Engineers seeking a proven LIU IC for T1/E1 interfaces or high-density telecom hardware will find this IC a technically sound choice.
