CD74ACT174PWR

Overview

The CD74ACT174PWR is a hex D-type flip-flop with reset from the Texas Instruments ACT logic family. It features six independent D-type flip-flops in a single package, providing positive-edge triggering and asynchronous active-low reset inputs for each stage. The device operates within a supply voltage range of 4.5 V to 5.5 V, ensuring compatibility with standard CMOS and TTL logic levels. Designed for surface-mount applications, it utilizes a TSSOP-16 package. The component supports high-speed data transfer with propagation delays typical of the ACT series, suitable for parallel-to-serial conversion and register storage in digital systems.

Feature Summary

• Integrates six independent D-type flip-flops with positive-edge clock triggering
• Includes asynchronous active-low reset inputs for immediate state clearing
• Supports direct interface with both CMOS and TTL logic families
• Optimized for high-speed data processing within industrial temperature ranges

Applications

• Parallel-to-serial data conversion circuits
• General-purpose register storage in digital systems
• Shift register configurations for data transmission
• Timing control and synchronization logic blocks

Procurement Notes

Verify that the ordering suffix matches the required package type, as variations exist between tube and reel packaging formats. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage specifications align with system requirements, as the ACT series typically requires a stable 5 V rail. Cross-reference the specific part number against current datasheets to validate pinout and electrical characteristics for the exact revision.

Selection Notes

Select this component when a compact solution for multiple synchronized storage elements is required without external wiring complexity. The ACT series offers superior speed compared to standard HC logic while maintaining low power consumption. Consider the TSSOP-16 package for space-constrained PCB layouts requiring surface-mount technology. Evaluate thermal performance and noise immunity needs, as the ACT family provides robust switching characteristics for high-frequency digital applications.

Part Context

This part belongs to the Texas Instruments CD74ACT174 series, which expands the classic 74ACT174 functionality into modern surface-mount packages. The ACT logic family bridges the performance gap between older bipolar technologies and newer CMOS standards, offering faster switching speeds than HC variants. This specific model represents the industry-standard hex D-flip-flop architecture adapted for contemporary manufacturing processes and automated assembly lines.

Replacement Considerations

Compatible substitutes include the CD74ACT174E (PDIP package) and CD74ACT174M96E4 (SOIC package). Verify pin compatibility and electrical parameters before substitution. Alternative logic families such as HC or HCT may require voltage level adjustments due to different switching thresholds.
