SN74AHCT174D

Flip Flops Overview

The SN74AHCT174D is a hex D-type flip-flop from the Texas Instruments AHC logic family, housed in a 16-pin SOIC package. It features six independent D-type flip-flops with a shared low-active clear input and positive-edge triggered clock inputs. The device operates within a supply voltage range of 2 V to 5.5 V, ensuring compatibility with standard CMOS logic levels. Key electrical characteristics include a maximum propagation delay of 14.5 ns at 5 V with a 50 pF load, and output drive capabilities of ±8 mA. It supports through-hole or surface-mount installation depending on the specific suffix variant, functioning reliably across an operating temperature range of -40°C to +85°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops sharing a common active-low clear function
• Positive-edge triggered data transfer synchronized to the clock signal
• CMOS compatible input and output structures for broad system integration

Flip Flops Applications

• Parallel data synchronization circuits
• Shift register configurations
• Mode generation logic systems

Flip Flops Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the selected variant matches the required thermal performance and mounting style for the target application design.

Flip Flops Selection Notes

Select this component when a high-speed hex D-type flip-flop with a global reset is required. The AHC series offers superior speed compared to standard HC logic while maintaining CMOS compatibility. Confirm that the input voltage levels align with the system's logic thresholds before finalizing the design.

Flip Flops Part Context

This part belongs to the SN74AHC174 family of hex D-type flip-flops. It shares functional similarities with other variants like the SN74AHCT174DR but differs in packaging and specific electrical testing conditions defined by the manufacturer's documentation.

Flip Flops Replacement Considerations

Direct substitutes include SN74AHCT174D and SN74AHCT174DB. Verify pinout compatibility and electrical parameters before swapping.
