SN74AS174N

Flip Flops Overview

The SN74AS174N is a hex D-type flip-flop from the Texas Instruments AS logic series, housed in a 16-pin PDIP package. It features positive-edge triggering and includes a master clear input. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 10 ns, a high-level output current of -2 mA, and a low-level output current of 20 mA. It supports through-hole mounting and functions within an operating temperature range of 0°C to +70°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops with positive-edge clock triggering
• Integrates a dedicated master clear input for synchronous reset functionality
• Utilizes TTL-compatible input and output interfaces for standard logic integration

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Timing control circuits requiring precise edge-triggered state changes

Flip Flops Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets RoHS requirements if applicable to the target assembly. Cross-reference the active status and lead times directly with authorized distributors to confirm availability for production schedules.

Flip Flops Selection Notes

Select this component when high-speed performance is required within standard TTL voltage levels. The AS series offers faster switching speeds compared to LS or ALS variants. Consider the PDIP package for prototyping or applications requiring manual insertion. Evaluate power consumption constraints as the AS series typically draws higher static current than CMOS alternatives.

Flip Flops Part Context

This part belongs to the SN74AS174 family of high-speed logic devices. It serves as a direct functional equivalent to other hex D-type flip-flops but distinguishes itself through superior speed characteristics inherent to the AS logic family. It complements related components like the SN74AS175 quad D-type flip-flop within the same product line.
