SN74LVT8986GGV

Specialty Logic Overview

The SN74LVT8986GGV is a 3.3-V Linking Addressable Scan Port (LASP) multidrop-addressable IEEE Std 1149.1 (JTAG) tap transceiver manufactured by Texas Instruments. It belongs to the SN74LVT8986 series and is designed for boundary scan testing applications. The device operates within an ambient temperature range of -40°C to +85°C. It is housed in a 64-pin MICROSTAR (8x8) BGA package, providing a compact form factor suitable for high-density PCB layouts.

Specialty Logic Feature Summary

• Supports multidrop addressing for efficient JTAG chain expansion
• Facilitates boundary scan testing of fully scannable devices
• Compatible with IEEE Std 1149.1 standards

Specialty Logic Applications

• Boundary scan testing infrastructure
• JTAG chain expansion in embedded systems
• Testing of fully boundary-scannable devices

Specialty Logic Procurement Notes

Verify the specific package variant against the datasheet, as the GG suffix denotes the 64-BGA MICROSTAR package. Confirm that the operating temperature range meets the system requirements of -40°C to +85°C. Ensure compatibility with 3.3-V logic levels for proper interface integration. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans.

Specialty Logic Selection Notes

Select this component when designing systems requiring multidrop addressable JTAG taps to reduce pin count and simplify chain topology. It is suitable for applications needing compliance with IEEE 1149.1 standards. Consider the 64-BGA package constraints for layout and thermal management. Compare with other LASP devices if different voltage levels or package types are required.

Specialty Logic Part Context

This part is part of the Texas Instruments family of IEEE Std 1149.1 (JTAG) scan-support products. These devices facilitate the testing of fully boundary-scannable devices by providing linking addressable scan ports. The SN74LVT8986 series specifically offers 3.3-V operation and multidrop addressing capabilities.

Specialty Logic Replacement Considerations

The SN74LVT8986GGV is listed as obsolete. Potential substitutes include the SN74LVT8986PM or SN74LVT8986GGV equivalents from authorized distributors, though availability may be limited. Verify functional equivalence and package compatibility before substitution.
