MT89L80AP1

Telecom Overview

The MT89L80AP1 is a digital bus switch IC manufactured by Microchip Technology. It operates within a supply voltage range of 4.75 V to 5.25 V and draws a typical supply current of 6 mA. The device supports an operating temperature range from -40°C to +85°C. It is housed in a 44-PLCC (J-Lead) surface-mount package, specifically identified as a 44-LCC with J-leads. This component functions as a single circuit switch designed for telecommunications applications.

Telecom Feature Summary

• Compatible with Zarlink ST-BUS standards
• Supports non-blocking switching architecture

Telecom Applications

• Telecommunications systems requiring digital bus switching
• ST-BUS compatible network interfaces
• Digital signal routing in communication equipment

Telecom Procurement Notes

Verify the specific suffix 'AP1' against official Microchip documentation to confirm package type and tape-and-reel or tube packaging details. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Check for product discontinuation notices or lifecycle changes before finalizing procurement plans.

Telecom Selection Notes

Select this component when a 44-pin PLCC package is required for ST-BUS compatible designs. Ensure the system power supply remains within the 4.75 V to 5.25 V range. Verify that the thermal environment stays within the specified -40°C to +85°C operational limits for reliable performance.

Telecom Part Context

This part belongs to the MT89xx family of digital bus switches. It shares functional similarities with other members like the MT8980 series but differs in pin count and specific interface configurations. The MT89L80AP1 is distinct from analog crosspoint switches such as the MT8809 series.

Telecom Replacement Considerations

Check for direct substitutes within the MT89xx family. Verify compatibility with existing PCB footprints for the 44-PLCC package. Confirm electrical parameter alignment for voltage and current specifications.
