74HC109D-Q100J

Overview

The Nexperia 74HC109D-Q100J is a dual D-type flip-flop with preset and clear, manufactured in the HC (High-speed CMOS) logic series. It is housed in a SOIC-16 surface-mount package and certified to AEC-Q100 standards for automotive reliability. The device operates within a supply voltage range of 2 V to 6 V, supporting a wide input voltage spectrum. Key electrical parameters include a propagation delay of 14 ns, a low-level output current of 5.2 mA, and a high-level output current of -5.2 mA. It functions reliably across an extended temperature range from -40 °C to +125 °C.

Feature Summary

• Dual D-type flip-flops integrated into a single compact package
• Automotive-grade qualification ensuring robust performance under harsh conditions
• Wide operating voltage range compatible with various system power rails

Applications

• Automotive electronic control units requiring reliable data storage
• Industrial automation systems utilizing standard logic interfaces
• Consumer electronics designs demanding extended temperature stability

Procurement Notes

Verify that the specific suffix Q100J corresponds to the required AEC-Q100 automotive grade certification and SOIC-16 packaging configuration. Confirm compatibility with your board's thermal management requirements given the +125 °C maximum junction temperature rating. Ensure input signal levels align with the specified 2 V to 6 V operating range to prevent undefined states or excessive current draw during operation.

Selection Notes

Select this component when dual independent D-flip-flops are needed with automotive reliability standards. The HC series offers high-speed switching suitable for general digital applications. Consider the SOIC-16 footprint for PCB layout constraints. Verify that the 2 V minimum supply voltage meets your system's lowest operating condition, as lower voltages may impact noise margins compared to higher voltage operations.

Part Context

This part belongs to Nexperia’s extensive portfolio of automotive-certified logic ICs designed for connected vehicles. The 74HC109 family provides essential sequential logic functions, while the -Q100 designation indicates compliance with strict automotive quality and reliability standards. It complements other logic gates and drivers within the same automotive catalog, facilitating complete digital circuit implementations in safety-critical environments.

Replacement Considerations

The 74HCT109D-Q100J serves as a functional substitute but requires a 4.5 V to 5.5 V supply due to TTL-compatible input thresholds. Ensure voltage level translation is addressed if replacing with HCT variants in 3.3 V systems. Direct pin-to-pin replacement is possible only if supply voltage and input logic levels match the original design specifications.
