MT8980DPR1

Telecom Overview

The MT8980DPR1 is a digital bus switch IC manufactured by Microchip Technology, designed for telecommunications applications. It features a non-blocking switching architecture with 44-LCC (J-lead) packaging in a 44-PLCC supplier device package. The device operates on a single +5 V power supply within a voltage range of 4.75V to 5.25V. It draws a typical supply current of 6mA and supports an operating temperature range from -40°C to 85°C. The component implements one circuit and is compatible with the Zarlink ST-BUS standard, supporting 8-line by 32-channel inputs and outputs.

Telecom Feature Summary

• Supports 256 ports of non-blocking switching capability
• Compatible with Zarlink ST-BUS interface standards
• Operates on a single positive five-volt power supply

Telecom Applications

• Telecommunications signal routing
• Digital bus switching systems
• ST-BUS compatible network interfaces

Telecom Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and tape/reel specifications. Ensure compatibility with existing PCB footprints for 44-LCC J-lead packages. Confirm RoHS compliance status through current datasheets or environmental reports before procurement.

Telecom Selection Notes

Select this component when a non-blocking digital switch with ST-BUS compatibility is required. Verify that the system design accommodates the 44-PLCC surface mount package dimensions. Ensure the power supply provides stable 5V regulation within the specified tolerance limits for reliable operation across the industrial temperature range.

Telecom Part Context

This part belongs to the MT8980 family of digital bus switches. It shares functional similarities with other variants like the MT8980DE1 but differs in packaging and distribution format. The MT8980 series is designed for high-density switching applications in telecom infrastructure.

Telecom Replacement Considerations

The MT8980DE1 is a related variant within the same product family. Verify pinout compatibility and package differences before substitution. No direct public substitute part numbers are confirmed for this specific PLCC configuration.
