MC145572AEI ISDN U-Interface Transceiver
TheMC145572AEI is a high-integration single-chip ISDN U-interface transceiver originally developed by Motorola (now NXP Semiconductors) and supplied by Rochester Electronics, housed in a 44-pin PLCC package for robust surface-mount deployment in telecommunications infrastructure. Designed to comply with ANSI T1.601-1992 and ETSI ETR 080 standards, this device supports both Line Termination (LT) and Network Termination (NT) modes, executing all Layer 1 physical layer functions for basic rate ISDN access with 2B1Q line coding, delivering a 160 kbps aggregate data rate (2×64 kbps B-channels + 1×16 kbps D-channel) over twisted-pair copper lines. Operating from a single 3V–5.5V supply with an industrial temperature range of –40°C to +85°C, it integrates on-chip line drivers, receivers, clock synthesis, and HDLC framing logic, eliminating the need for external analog front-end components and simplifying ISDN system design.
Choosing the MC145572AEI delivers unmatched integration, compliance, and longevity for ISDN system design:
● Its single-chip integration eliminates dozens of discrete components, reducing BOM cost, PCB space, and assembly complexity
● Strict ANSI/ETSI compliance ensures seamless interoperability with global ISDN networks, critical for telecom equipment certification and deployment
● The 44-pin PLCC package offers a robust, industry-standard form factor for reliable surface-mount assembly and long-term durability
● Rochester Electronics' authorized supply and lifecycle support mitigate obsolescence risks for legacy telecom system maintenance
● Comprehensive design resources, including evaluation boards and detailed datasheets, accelerate prototyping and system integration
● Low power consumption and wide supply voltage range enhance flexibility in both mains-powered and battery-operated ISDN devices.
Alternative interface IC Components
● MC145572AFN: A 44-PLCC ISDN U-interface transceiver with identical functionality, optimized for extended temperature range industrial applications.
● MC145572AAC: A 44-LQFP surface-mount variant offering reduced package size and improved thermal performance for space-constrained telecom line cards.
● AM79C30A: A low-power ISDN S/T-interface transceiver supporting 2B+D data rates, ideal for cost-sensitive CPE and small-office ISDN devices.
● STLC5440: A multi-channel ISDN transceiver with integrated line drivers, designed for high-density central office line card applications.
