74174PC

Flip Flops Overview

The National Semiconductor 74174PC is a hex D-type flip-flop integrated circuit belonging to the standard 7400 logic series. It features six independent D-type flip-flops with non-inverting outputs and an active-low asynchronous clear input. The device operates within a supply voltage range of 2V to 6V, supporting both TTL and CMOS logic families. It exhibits a typical propagation delay of 25 nanoseconds and is housed in a 16-pin PDIP package suitable for through-hole mounting.

Flip Flops Feature Summary

• Contains six independent D-type flip-flops for parallel data storage
• Includes an active-low asynchronous clear function for immediate reset
• Provides non-inverting outputs compatible with standard logic levels

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• State machine implementation

Flip Flops Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity and pin alignment against original specifications. Check datasheet revisions for electrical parameter updates. Ensure compatibility with existing board layouts before integration.

Flip Flops Selection Notes

Select this component for designs requiring multiple independent storage elements within a single package. Consider the 25ns propagation delay for timing constraints. Verify that the 16-pin DIP footprint matches the target PCB design requirements.

Flip Flops Part Context

This part belongs to the widely adopted 7400 series of digital logic ICs. It serves as a fundamental building block for sequential logic circuits. The hex configuration allows for compact implementation of multi-bit storage functions compared to using individual single flip-flop devices.

Flip Flops Replacement Considerations

Direct substitutes include the SN74174 from Texas Instruments. Other manufacturers may offer equivalent parts under different numbering schemes. Verify pinout compatibility and electrical characteristics before substitution.
