74F676SC

Overview

The 74F676SC is a Parallel In Serial Out shift register belonging to the F/FAST series. It features a 16-bit width with right-direction shifting capability and true output polarity. The device operates within TTL logic levels and utilizes a 28-pin Plastic Quad Flat Package (QCCJ) construction. Key electrical characteristics include a propagation delay of 13.5 ns, an operating temperature range up to 70 °C, and a maximum supply current of 20 mA. The package dimensions are approximately 11.5 mm in length with a maximum height of 4.57 mm.

Feature Summary

• Parallel-to-serial data conversion functionality
• Right-direction bit shifting operation
• TTL-compatible input and output levels

Applications

• Data serialization for communication interfaces
• Parallel-to-serial conversion in digital systems
• Shift register stages in control logic circuits

Procurement Notes

Verify the specific suffix 'SC' against the manufacturer's official datasheet to confirm pinout compatibility and package variant accuracy. Ensure the component meets required environmental specifications for the intended application environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when parallel-to-serial conversion is required with high-speed performance typical of the F/FAST series. Consider the 16-bit capacity and right-shift direction for system architecture alignment. Verify that the TTL voltage levels match the surrounding circuitry requirements and that the QCCJ package fits the PCB layout constraints.

Part Context

This component is part of Fairchild's F/FAST logic family, designed for high-speed digital applications. It serves as a specialized shift register within the broader portfolio of logic integrated circuits. The device complements other serial interface components by providing efficient data format conversion capabilities.

Replacement Considerations

Check for direct pin-compatible alternatives from the same manufacturer or other vendors offering equivalent F/FAST series specifications. Verify that any substitute maintains the same 16-bit width, right-shift direction, and TTL compatibility.
