Procurement Notes
Verify the specific suffix 'Q100' confirms AEC-Q100 Grade 1 automotive qualification. Confirm the 'D' suffix indicates the SO16 package variant. Ensure compatibility with 4.5V to 5.5V supply rails. Check for RoHS compliance documentation. Validate lead times as automotive parts may have extended production cycles.
Selection Notes
Select this component when automotive reliability and high-speed performance are required. It is suitable for designs needing 4-bit storage with tri-state output control. Consider the 16-SO package for surface-mount assembly. Verify that the TTL input thresholds match the system logic levels. Ensure thermal management supports the -40°C to +125°C operating range.
Part Context
This part belongs to the Nexperia 74HCT series, which combines high-speed CMOS performance with TTL-compatible inputs. The Q100 designation signifies automotive qualification, distinguishing it from standard commercial variants. It serves as a fundamental building block for sequential logic in robust electronic systems.
Replacement Considerations
Check for other 74HCT173 variants with different package options or qualification grades. Verify pin-to-pin compatibility with alternative manufacturers' 4-bit D-type flip-flops. Ensure electrical parameters such as propagation delay and output drive current meet design requirements.
