DM74ALS874BWM

Overview

The DM74ALS874BWM is a D-type flip-flop with positive-edge triggering, manufactured by Fairchild Semiconductor. It features an asynchronous active-low reset input and operates within a standard TTL voltage range of 4.5V to 5.5V. The device is housed in a 16-lead Small Outline Integrated Circuit (SOIC) package, specifically the MS-012 narrow body format. This component belongs to the Advanced Low-Power Schottky (ALS) logic family, designed for applications requiring improved switching performance and reduced power dissipation compared to standard Schottky counterparts.

Feature Summary

• Positive-edge triggered data storage mechanism
• Asynchronous active-low reset functionality
• Advanced oxide-isolated ion-implanted Schottky process

Applications

• Digital data storage registers
• Shift register configurations
• Timing control circuits

Procurement Notes

Verify the manufacturer origin, as Fairchild's semiconductor assets were acquired by ON Semiconductor. Confirm that the specific suffix 'BWM' corresponds to the SOIC-16 package variant. Ensure compliance with current RoHS directives and check for lead-free markings consistent with the '_NL' or equivalent environmental designations found in modern equivalents.

Selection Notes

Select this component when a single-bit memory element with immediate reset capability is required. The ALS family offers a balance between speed and power consumption suitable for general-purpose digital systems. Consider pin-compatible alternatives from the AS or LS families if higher drive current or different propagation delay characteristics are needed for the specific application timing constraints.

Part Context

This part is a member of the 74ALS series, which utilizes advanced Schottky technology to achieve lower power usage while maintaining high-speed operation. It serves as a fundamental building block in sequential logic design. The device provides reliable data retention and clear states, making it essential for synchronous digital systems where precise clock edge alignment and immediate initialization are critical requirements.
