SN74ABT8652DLR

Specialty Logic Overview

The SN74ABT8652DLR is a scan test device featuring octal bus transceivers and registers, manufactured using BiCMOS technology. It supports IEEE Standard 1149.1-1990 boundary-scan architecture via a four-wire Test Access Port (TAP). The device operates within a supply voltage range of 4.5 V to 5.5 V and functions across an industrial temperature range of -40°C to +85°C. It utilizes SSOP-28 packaging.

Specialty Logic Feature Summary

• Integrates octal bus transceivers with registers for normal data flow management alongside dedicated test circuitry.
• Supports IEEE Standard 1149.1-1990 boundary-scan testing through a four-wire TAP interface.
• Enables parallel-signature analysis and pseudo-random pattern generation for internal self-testing.
• Maintains functional equivalence to standard octal bus transceivers during normal operation modes.

Specialty Logic Applications

• Testing complex circuit-board assemblies utilizing boundary-scan architectures
• System-level diagnostic operations requiring non-intrusive I/O monitoring
• Manufacturing test environments implementing JTAG-compliant protocols

Specialty Logic Procurement Notes

Verify the specific package suffix 'DL' corresponds to the Shrink Small-Outline Package variant required for your design. Confirm that the operating environment remains within the specified -40°C to +85°C range. Ensure the system power supply strictly adheres to the 4.5 V to 5.5 V limits to maintain signal integrity and prevent device damage.

Specialty Logic Selection Notes

Select this component when board-level testing requirements mandate compliance with IEEE 1149.1 standards. It is suitable for designs needing simultaneous high-speed data transfer and comprehensive boundary-scan coverage. Consider the SSOP-28 footprint constraints and BiCMOS power characteristics relative to alternative logic families.

Specialty Logic Part Context

This device belongs to the Texas Instruments SCOPE family of testability products. It provides enhanced diagnostic capabilities compared to standard logic devices by embedding test structures directly into the bus transceiver functionality. The part serves as a bridge between standard digital interconnects and standardized test access methodologies.

Specialty Logic Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing boundary-scan controllers before attempting substitution with other members of the ABT logic family.
