DM74LS174M

Overview

The DM74LS174M is a hex D-type flip-flop manufactured by onsemi, belonging to the 74LS logic series. It features six positive-edge-triggered D-type flip-flops with a common clear input within a single package. The device operates on a supply voltage range of 4.75 V to 5.25 V and supports surface mount installation in a 14-SOIC package. It functions as a fundamental memory element for sequential logic circuits.

Feature Summary

• Contains six independent positive-edge-triggered D-type flip-flops
• Features a shared active-low clear input for synchronous reset
• Utilizes standard TTL circuitry for reliable digital signal processing

Applications

• Parallel data storage registers
• Shift register construction
• Sequential logic control systems

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as older manufacturing runs may not meet current environmental standards. Validate package integrity upon receipt to ensure proper pin alignment for SOIC-14 mounting.

Selection Notes

Select this component when designing circuits requiring multiple synchronized storage elements without individual clock inputs. Ensure the design accommodates the specific propagation delay characteristics inherent to the LS logic family. Verify that the system power supply remains stable within the specified operating voltage range.

Part Context
