MT8980DP1

Telecom Overview

The MT8980DP1 is a digital bus switch IC manufactured by Microchip Technology, designed for telecommunications applications. It functions as a non-blocking switch with an 8-line by 32-channel input and output configuration, supporting 256 ports. The device operates on a single +5 V power supply, consuming approximately 30 mW of typical power. It features Zarlink ST-BUS compatibility and is housed in a 44-PLCC (J-leaded) surface-mount package. The component supports a supply voltage range of 4.75V to 5.25V and draws 6mA of supply current.

Telecom Procurement Notes

Verify the specific suffix DP1 against official Microchip documentation to confirm package type and lead form. Ensure the component meets RoHS requirements if applicable to the target assembly process. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices before finalizing procurement plans.

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 package dimensions and the specified 4.75V to 5.25V operating voltage range. Confirm that the 6mA supply current fits within the overall power budget constraints of the application.

Telecom Part Context

This part belongs to the MT8980 family of digital bus switches from Microchip Technology. It serves as a specialized interface solution for connecting multiple lines and channels in telecommunications environments. The device provides a compact alternative to discrete switching matrices, integrating complex routing logic into a single integrated circuit package.

Telecom Replacement Considerations

Check for direct pin-compatible substitutes within the same MT8980 series or equivalent ST-BUS compatible switches from other manufacturers. Verify electrical parameters such as supply voltage and current consumption to ensure functional equivalence in existing designs.
