74VHC175SJ

Overview

The Fairchild Semiconductor 74VHC175SJ is an advanced high-speed CMOS quad D-type flip-flop fabricated with silicon gate technology. It features positive-edge triggering and includes a master reset input. The device provides three-state outputs for bus-oriented applications. It operates within a supply voltage range of 2.0 V to 5.5 V, ensuring compatibility with standard logic families while maintaining low power dissipation characteristics typical of CMOS devices.

Feature Summary

• Advanced high-speed CMOS fabrication enables operation comparable to Bipolar Schottky TTL
• Positive-edge triggered quad D-type configuration with dedicated master reset control
• Three-state outputs facilitate direct connection to system buses without additional drivers

Applications

• Bus-oriented memory register implementations
• 8-bit word storage in data processing systems
• Isolated storage registers for communication interfaces

Procurement Notes

Verify the specific suffix 'SJ' against official datasheets to confirm package type and tape-and-reel specifications. Ensure the component meets required RoHS compliance standards for the target application. Cross-reference the manufacturer part number with current onsemi or fairchild documentation to confirm availability status and pinout integrity before integration.

Selection Notes

Select this component when high switching speeds are required alongside low static power consumption. The wide operating voltage range supports both 3.3 V and 5 V logic environments. The inclusion of a master reset simplifies system initialization sequences compared to variants lacking this control input.

Part Context

This device belongs to the 74VHC series, representing an evolution of the standard 74HC logic family. It offers improved speed performance while retaining functional compatibility with existing 74HC designs. The quad D-type architecture allows for compact implementation of multi-bit state retention circuits in modern digital designs.

Replacement Considerations

The 74VHC175MTC serves as a verified surface-mount alternative within the same series. Both components share identical logical functionality and electrical characteristics. Verify package dimensions and thermal requirements when substituting between different physical form factors.
