74FR1074PC

Overview

The Fairchild Semiconductor 74FR1074PC is a dual D-type flip-flop belonging to the FR/FASTR series. It features positive-edge triggering and TTL-compatible inputs. The device provides both true and complementary outputs with high current drive capabilities, sinking and sourcing up to 24 mA. It is housed in a 14-lead Plastic Dual-In-Line Package (PDIP) with a standard .300-inch width.

Feature Summary

• Dual independent positive-edge-triggered D flip-flops
• High-current output drive capability of 24 mA source and sink
• Complementary true and inverted output states

Applications

• Parallel data storage registers
• Shift register construction
• Frequency division circuits

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm package integrity and pin alignment against the JEDEC MS-001 specification for the 14-lead PDIP format. Ensure compliance with relevant environmental standards prior to integration into final assemblies.

Selection Notes

Select this component when high-speed logic operation combined with robust output drive is required. The FR/FASTR series offers superior performance over standard LS logic. Verify that the application voltage levels align with TTL input thresholds and that the thermal environment supports the specified operating range.

Part Context

This part is part of the 74FR family, designed for high-speed applications requiring fast propagation delays. It serves as a direct functional replacement for other dual D-flip-flop devices within the broader 74xx logic ecosystem, specifically targeting systems needing enhanced speed and drive strength compared to legacy technologies.

Replacement Considerations

The 74FR74SCX is a documented equivalent offering identical logical functionality in a surface-mount SOIC package. Pin compatibility must be verified if transitioning between DIP and SOIC form factors.
