74FR1074SC

Overview

The 74FR1074SC is a dual D-type flip-flop manufactured by Fairchild Semiconductor. It features two independent positive-edge-triggered functions with set and reset inputs, housed in a 14-lead Small Outline Integrated Circuit (SOIC) package. The device provides true outputs capable of sinking and sourcing 24 mA. It operates within a specified temperature range up to 70 °C and utilizes plastic/epoxy packaging material.

Feature Summary

• Dual D-type flip-flop architecture with independent set and reset control
• Positive-edge triggering mechanism for data capture
• High current drive capability with 24 mA sink and source capacity
• Guaranteed pin-to-pin skew specifications for timing accuracy

Applications

• General-purpose digital logic storage applications
• Parallel-to-serial data conversion circuits
• Shift register implementations
• Timing and delay line circuits

Procurement Notes

Verify the specific suffix 'SC' against the manufacturer's official datasheet to confirm the exact package variant and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements if applicable to your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a dual D-type flip-flop with high current drive is required. The 14-lead SOIC package offers a compact solution for surface-mount designs. Consider the 24 mA output capability for direct driving of loads without additional buffering. Verify that the positive-edge trigger aligns with your system clocking scheme.

Part Context

This component belongs to the FR/FASTR series of high-speed logic devices from Fairchild Semiconductor. It is functionally related to the 74FR74 but packaged in a 14-lead SOIC format. The series is designed for TTL-compatible operations with enhanced performance characteristics suitable for bus-oriented and general-purpose digital applications.

Replacement Considerations

The 74FR74SCX is a documented substitute offering identical dual D-type functionality in a compatible 14-lead SOP package. Verify pin compatibility and electrical specifications before substitution.
