SN74ALS174D

Flip Flops Overview

The SN74ALS174D is a hex D-type positive-edge-triggered flip-flop manufactured by Texas Instruments in the ALS logic series. It features six independent D-type flip-flops with a common clear input, housed in a 16-pin SOIC package. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports data rates up to 50 MHz at nominal supply. It functions reliably across an operating temperature range of 0°C to 70°C.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops with positive-edge triggering
• Includes a common asynchronous clear input for all stages
• Compatible with standard 5 V CMOS logic families

Flip Flops Applications

• Parallel-to-serial data conversion circuits
• Shift register implementations
• General-purpose digital storage applications

Flip Flops Procurement Notes

Verify the specific suffix 'D' corresponds to the SOIC-16 package variant when sourcing. Confirm RoHS compliance status as indicated by manufacturer documentation. Ensure the component meets the required operating temperature range for the intended application environment before procurement.

Flip Flops Selection Notes

Select this component for designs requiring multiple synchronized storage elements within a single integrated circuit. Consider the ALS series characteristics regarding speed and power consumption relative to other logic families. Verify that the 16-pin SOIC footprint aligns with the printed circuit board layout constraints.

Flip Flops Part Context

This part belongs to the Texas Instruments 74ALS logic family, which offers higher speed performance compared to standard 74LS devices while maintaining lower power consumption than 74AS variants. The SN74ALS174 specifically provides hex flip-flop functionality, distinguishing it from quad or octal configurations available in related product lines.

Flip Flops Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74ALS174N (PDIP) or SN74ALS174DR (tape and reel). Verify functional equivalence with other hex D-type flip-flops from different manufacturers if package changes are necessary.
