DM74AS874WMX

Overview

The DM74AS874WMX is a dual 4-bit D-type flip-flop manufactured by Fairchild Semiconductor, housed in a 24-SOIC package. It operates on a supply voltage of 4.5V to 5.5V and features positive edge triggering with a master reset function. The device is RoHS compliant and designed for high-speed digital applications within the AS logic series.

Feature Summary

• Dual 4-bit configuration providing eight independent storage elements
• Positive edge-triggered data capture mechanism
• Integrated master reset functionality for synchronous initialization

Applications

• Digital data storage circuits
• Shift register implementations
• Counters and timing control systems

Procurement Notes

Verify component authenticity through official Fairchild or authorized distributor channels. Confirm RoHS compliance status matches current regulatory requirements. Ensure the 24-SOIC package dimensions align with PCB footprint specifications before integration into final assembly designs.

Selection Notes

Select this component for applications requiring dual 4-bit storage with synchronous reset capabilities. The AS series offers higher speed performance compared to standard TTL variants. Verify that the 4.5V to 5.5V supply range fits the system power architecture and that the SOIC package suits the manufacturing process.

Part Context

This part belongs to the Fairchild AS logic family, characterized by advanced Schottky technology for improved switching speeds. The DM74AS874WMX specifically provides dual 4-bit D-type flip-flops, distinguishing it from single-bit or wider bus transceiver components within the broader semiconductor portfolio.

Replacement Considerations

Consult official cross-reference guides for equivalent dual 4-bit D-type flip-flops in the 24-SOIC package. Verify pin compatibility and electrical characteristics when substituting with other manufacturers' AS series devices.
