74F574SCX

Flip Flops Overview

The Fairchild Semiconductor 74F574SCX is an octal D-type flip-flop belonging to the F/FAST logic series. It features eight independent D-type flip-flops with three-state outputs, designed for high-speed digital applications. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports through-hole mounting in a standard DIP-20 package. It provides non-inverting output polarity and includes a common clock input for synchronous data storage.

Flip Flops Feature Summary

• Octal configuration containing eight independent D-type flip-flops
• Three-state outputs suitable for bus-oriented system architectures
• High-speed F/FAST logic family performance characteristics
• Common clock input for synchronized data capture

Flip Flops Applications

• Bus driver circuits requiring high-speed data transfer
• Input or output port interfaces for microprocessor systems
• General-purpose register implementations in digital logic designs
• Data latch applications in communication equipment

Flip Flops Procurement Notes

Verify the specific manufacturer origin, as Fairchild Semiconductor's logic division was acquired by onsemi. Confirm that the part number suffix matches the intended plastic SOP packaging variant rather than ceramic or other package types. Ensure compliance with current RoHS directives and check for any obsolescence notices from the current rights holder before finalizing procurement specifications.

Flip Flops Selection Notes

Select this component when an octal register with tri-state capability is required within the F/FAST speed class. Compare against the SN74F574N for equivalent functionality in different package formats. Consider the 74ACT574 if lower power consumption and CMOS compatibility are prioritized over the specific propagation delay characteristics of the F-series technology.

Flip Flops Part Context

This device belongs to the industry-standard 74F logic family, known for fast switching speeds compared to earlier TTL variants. The 74F574 specifically addresses the need for wide data path storage with isolation capabilities. It serves as a fundamental building block for parallel data handling in legacy and industrial digital control systems.

Flip Flops Replacement Considerations

The SN74F574N offers identical logical function in a PDIP-20 package. For surface-mount requirements, verify availability of the SCX suffix variant from current manufacturers. Cross-reference with 74FCT574AFC for faster CMOS-based alternatives if system voltage levels permit.
