SN74LVT8996IPWREP

Specialty Logic Overview

The SN74LVT8996IPWREP is a 3.3V, 10-bit Addressable Scan Port (ASP) multi-add tap transceiver from Texas Instruments' SCOPE family. Designed for IEEE Std 1149.1 (JTAG) boundary scan applications, it extends test access beyond the board level by connecting module-level TAPs to higher-level inter-module TAPs. The device operates within a voltage range of 2.7V to 3.6V and supports an operating temperature range of -55°C to +125°C. It features a TSSOP-24 package and provides high drive outputs with latch-up protection exceeding JESD 78 Class II requirements.

Specialty Logic Feature Summary

• Supports IEEE Std 1149.1-1990 boundary scan standards for complex circuit testing
• Enables multi-branch routing of all five JTAG signals to overcome ring and star configuration limitations
• Provides 10-bit address space allowing up to 1021 user-specified board addresses plus three global addresses
• Features robust ESD protection and high drive output capability for backplane interfaces

Specialty Logic Applications

• Extending JTAG test access from module level to system level in complex electronic assemblies
• Interfacing 3.3V devices with 5V main equipment or target devices in mixed-voltage environments
• Facilitating board-level and system-level boundary scan testing for manufacturing validation

Specialty Logic Procurement Notes

Verify that the specific suffix 'IPWREP' corresponds to the industrial temperature grade (-55°C to +125°C) and tape-and-reel packaging format. Confirm RoHS compliance status and ensure the ordering part number matches the exact package type required for your PCB footprint. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices before finalizing procurement.

Specialty Logic Selection Notes

Select this component when designing systems requiring scalable JTAG infrastructure across multiple modules. It is suitable for environments demanding wide industrial temperature ranges and high noise immunity. Ensure the design accommodates the 10-bit addressing scheme and verify that the 3.3V logic levels are compatible with the connected TAP controllers and target devices.

Specialty Logic Part Context

This device belongs to Texas Instruments' SCOPE (System Component On-board Programmable Evaluation) family of specialty function logic. It complements standard boundary scan cells by providing external connectivity for test signals. The SN74LVT8996 series is distinct from standard logic ICs as it specifically manages test access port topology rather than performing general data processing functions.
