SN74BCT8374ADWRG4

Specialty Logic Overview

The SN74BCT8374ADWRG4 is an octal D-type edge-triggered flip-flop scan test device manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and features three-state outputs. The component utilizes a 24-pin SOIC package and supports surface-mount installation. It is designed for high-speed applications with propagation delays characteristic of the BCT logic family, ensuring reliable data storage and transfer in digital systems.

Specialty Logic Feature Summary

• Integrates eight D-type edge-triggered flip-flops for parallel data handling
• Includes dedicated scan test architecture for enhanced manufacturing verification
• Provides three-state outputs to facilitate bus-oriented connections

Specialty Logic Applications

• Digital system scan chain testing
• High-speed data storage registers
• Bus interface circuitry requiring tri-state control

Specialty Logic Procurement Notes

Verify the complete part number including the G4 suffix to confirm RoHS compliance and lead-free status. Ensure the SOIC-24 package dimensions match the target PCB footprint. Confirm that the 4.5V to 5.5V operating voltage aligns with the system power supply specifications before integration.

Specialty Logic Selection Notes

Select this component when scan test functionality is required alongside standard octal flip-flop operations. It is suitable for designs needing high drive capability and fast switching speeds compared to standard HC logic. Verify compatibility with existing clocking schemes and ensure thermal management meets the requirements for the SOIC-24 package.

Specialty Logic Part Context

This device belongs to the SN74BCT series, which combines BiCMOS technology for high speed with CMOS low power consumption. Unlike the SN74ABT374ADWRG4, which lacks scan test features, this model includes specific test structures. It differs from the SN74HC374DWR by offering superior speed and current drive capabilities while maintaining similar pin configurations for certain applications.

Specialty Logic Replacement Considerations

The SN74BCT8374ADW is a non-compliant variant of the same functional device. For RoHS-compliant replacements, verify availability of the SN74BCT8374ADWRG4 or equivalent scan-capable octal flip-flops from other manufacturers supporting the 24-SOIC package.
