74AC174PC

Flip Flops Overview

The Fairchild Semiconductor 74AC174PC is a hex D-type flip-flop housed in a 16-pin plastic DIP package. It operates within a supply voltage range of 2.0V to 6.0V and supports a maximum operating frequency of 70MHz at 5V. The device features TTL-compatible inputs, outputs capable of sourcing and sinking 24mA, and includes a master reset function to simultaneously clear all flip-flops. It is designed for high-speed, low-power applications with an operating temperature range of -40°C to 85°C.

Flip Flops Feature Summary

• Hex D-type flip-flop architecture with master reset functionality
• TTL-compatible inputs for direct interfacing with standard logic families
• High-drive output capability supporting bus-oriented applications

Flip Flops Applications

• Parallel data storage registers
• Shift register configurations
• Timing delay circuits

Flip Flops Procurement Notes

Verify the specific manufacturer source, as Fairchild Semiconductor operations were acquired by onsemi. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to assembly. Ensure the component matches the required lead-free specifications for modern manufacturing processes. Check for any obsolescence notices or lifecycle changes that may affect long-term availability.

Flip Flops Selection Notes

Select this component when a hex D-type flip-flop with a global reset is required. It is suitable for designs needing TTL input compatibility and moderate drive strength. Consider the 16-pin DIP package for through-hole prototyping or legacy board layouts. Evaluate power consumption requirements against the AC series specifications.

Flip Flops Part Context

This part belongs to the 74AC logic family, known for high speed and low power consumption compared to earlier CMOS standards. The 74AC174 variant specifically provides six independent D-type flip-flops within a single package. It serves as a fundamental building block for sequential logic circuits in digital systems requiring parallel data handling.

Flip Flops Replacement Considerations

Equivalent parts include the 74ACT174PC for TTL-compatible input variations and the 74HC174PC for general-purpose CMOS applications. Cross-reference pinouts and electrical characteristics carefully to ensure functional compatibility in existing designs.
