DM74ALS174M

Overview

The DM74ALS174M is a Hex D-Type Flip-Flop from the Advanced Low-Power Schottky (ALS) logic family, manufactured by Fairchild Semiconductor. It features six independent positive-edge-triggered flip-flops with true outputs and a common direct clear input. The device operates within a supply voltage range of 4.5V to 5.5V and supports a typical clock frequency of 50 MHz. It utilizes a 16-pin Small Outline Integrated Circuit (SOIC) package.

Feature Summary

• Contains six independent D-type flip-flops with single-rail outputs
• Features buffered clock and direct clear inputs for signal integrity
• Advanced Low-Power Schottky technology ensures improved switching speed and reduced power consumption

Applications

• Buffer and storage registers in digital systems
• Shift register configurations for data movement
• Pattern generators for test and measurement equipment

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific part number matches the required ALS logic family specifications and SOIC-16 package dimensions. Ensure compliance with RoHS directives if applicable to the target application environment.

Selection Notes

Select this component when high-speed operation and low power dissipation are critical requirements. The ALS series offers superior performance compared to standard LS logic while maintaining compatible pinouts. Consider the 50 MHz clock capability and direct clear functionality for synchronous design architectures requiring precise timing control.

Part Context

This component belongs to the 74ALS logic family, representing an evolution of the standard 74LS series with enhanced performance characteristics. The DM prefix indicates a commercial temperature grade variant. As part of the widely adopted 74xx series, it serves as a fundamental building block for sequential logic circuits in various electronic systems.

Replacement Considerations

SN74ALS174NSR is a confirmed direct substitute from Texas Instruments. Verify pin compatibility and electrical parameter alignment before implementation.
